CEDRUS DEODARA AT GLENGARRA<br />
By O. V. MOONEY, B.AGR.SC.<br />
THE subject <strong>of</strong> this note is a small but remarkable stand <strong>of</strong> Cedrus<br />
Deodara which is situated on the side <strong>of</strong> a remote mountain valley<br />
which cuts deep into the southern slopes <strong>of</strong> the Galtee Mountains in<br />
Tipperary. This stand is now the property <strong>of</strong> the Dept. <strong>of</strong> Lands,<br />
Forestry Division and forms part <strong>of</strong> Glengarra Forest.<br />
Location.<br />
<strong>The</strong> approach on the ground can be found through a lodge gate<br />
just south-west <strong>of</strong> Glengarra bridge, which is situated about half-way<br />
between Mitchelstown and Cahir on the main Dublin-Cork road.<br />
Cahir, which is a little nearer than Mitchelsown, is about nine miles<br />
from Glengarra bridge. <strong>The</strong> way from the main road to the Cedar<br />
stand (which is really an old avenue) is nothwards along the bottom<br />
<strong>of</strong> a most impressively beautiful river valley where some remarkably<br />
fine specimens <strong>of</strong> Scots Pine, European Larch, Norway Spruce,<br />
Silver Fir and Cedar can be seen in passing; but the walk is most<br />
renowned, and very rightly so, for the range and magnificence <strong>of</strong> its<br />
bordering rhododendrons the splendour <strong>of</strong> whose flowers in spring<br />
can only be underrated by any attempted description. <strong>The</strong> avenue<br />
finally comes to an end at an old shooting lodge known as Mountain<br />
Lodge (nearly two miles from the main road) and now an An Oige<br />
hostel. <strong>The</strong> place is very well worth a visit. <strong>The</strong> river <strong>of</strong> this valley<br />
is the Burncourt river whose source is a little more than two miles<br />
further to the north-west at the foot <strong>of</strong> the Galteemore peak 3,018'.<br />
History and Past Treatment.<br />
Of the early history <strong>of</strong> this stand nothing concrete could be found<br />
as no records were procurable. This is greatly to be regretted as an<br />
account <strong>of</strong> any stand is incomplete unless accurate recordings <strong>of</strong> some<br />
sort can be made, <strong>of</strong> the origin <strong>of</strong> seed and plants, the type <strong>of</strong> ground<br />
planted, the method <strong>of</strong> planting, and so on.<br />
<strong>The</strong> planting was done some seventy years ago by the Butler family<br />
<strong>of</strong> Shanbally who owned the woods in the locality up to recent times.<br />
<strong>The</strong> planting lines appear to have run across the slope and, though
-I<br />
there is not sufficient evidence to deduce the exact spacing <strong>of</strong> the<br />
original planting, there are indications that the plants were put in at<br />
six feet apart. <strong>The</strong>re are prominent flattened ridges within the wood<br />
running up and down the slope <strong>of</strong> the ground which would seem to<br />
suggest that the ground was cultivated at one time, probably by potato<br />
drills, but at first sight these ridges were associated with the method<br />
<strong>of</strong> planting. <strong>The</strong>re is nothing with which to fill the gap between 1880<br />
and about ten years ago when the Dept. high-pruned the area then<br />
owned by them to about 20'. Apart from this operation nothing was<br />
done since except to cut windfalls <strong>of</strong>f root when they blew down in<br />
the valley bottom where there is a patch <strong>of</strong> s<strong>of</strong>t ground.<br />
Climate.<br />
<strong>The</strong> annual rainfall for the locality is about 45". Heavy falls <strong>of</strong><br />
snow are not usual but the high lying ground <strong>of</strong> the district is subject<br />
to occasional south-westerly gales <strong>of</strong> high velocity.<br />
Soil and Vegetation.<br />
<strong>The</strong> soil is Old Red Sandstone drift-a light stony well-drained<br />
soil <strong>of</strong> good depth. A shallow 4" layer <strong>of</strong> brown earth seems to be<br />
prevalent at the surface. Over this there is a raw humus layer <strong>of</strong> I"<br />
to I!" in which there seems to have been exceptionally little<br />
decomposition <strong>of</strong> the needles and the line between it and the surface<br />
<strong>of</strong> the mineral soil appears particularly sharp. Podsolisation was not<br />
evident. <strong>The</strong> vegetation in the wood is sparse and is mainly composed<br />
<strong>of</strong> a moss carpet in which Polytrichum was prominent and occasional<br />
small herbs <strong>of</strong> which Oxalis was most noticeable. Taller plants were<br />
represented mainly by erratic bracken (Pteris), briar (Rubus) and foxglove<br />
(Digitalis). <strong>The</strong> vegetation outside the wood on the north side<br />
was luxuriant with grasses, briar and bracken.<br />
Aspect and Elevation.<br />
<strong>The</strong> aspect <strong>of</strong> the ground is south-westerly on a steep slope which<br />
rises from about 680' at the lower side <strong>of</strong> the stand to about 760' at<br />
the upper edge. <strong>The</strong> wood is not very exposed except on its N.E.<br />
side where it is open to north and easterly winds.<br />
<strong>The</strong> Stand.<br />
<strong>The</strong> wood covers about I! acres and one's first impression is <strong>of</strong><br />
a vigorous healthy stand with an ideal amount <strong>of</strong> growing space for<br />
each tree. This impression is confirmed by more detailed examination<br />
and though the growth in general has fallen <strong>of</strong>f in recent years the<br />
leaders and crowns <strong>of</strong> the trees have a very healthy and vigorous<br />
appearance. As mentioned before one part <strong>of</strong> the stand has been<br />
pruned up to about 20' but the remainder (which was only recently<br />
acquired by the Dept.) was not pruned. In the latter area dead but<br />
firmly attached branches are retained on the trees almost down to
ground level. This fact tog;:,:1e, with other observations suggests that<br />
the stand was unduly open from an early stage in its life. <strong>The</strong><br />
average tree bears a live crown down to from 35 to 40 feet above the<br />
ground but the canopy is only semi-closed and there is abundant light<br />
in the stand which fact contrasts strangely with the sparse vegetation<br />
on the floor <strong>of</strong> the wood. Although it is now about 10 years since<br />
the pruning was done the bark has not closed over the pruned<br />
branches- due no doubt to the age <strong>of</strong> the trees and in lesser part to<br />
the old branches which were abnormally thick for pruning.<br />
About 12 % <strong>of</strong> the trees in this wood are forked low down at<br />
from 2' to 4' above ground level and many roots bear two fine tall<br />
stems (7" to 9:i" Q.G.B.H. X 50' Approx.). Whether this forking is<br />
due to some damage by animals or weather in early life or to the<br />
natural habit <strong>of</strong> the species is not known.<br />
<strong>The</strong> taper <strong>of</strong> the Cedars, in spite <strong>of</strong> their age, appears to be small,<br />
but no detailed investigation into this quality <strong>of</strong> the crop could be<br />
achieved. Random Pressler borings <strong>of</strong> average sized trees revealed<br />
periodic ring growth similar in pattern to European larch. In the<br />
absence <strong>of</strong> sufficient span to illustrate this may best be indicated as<br />
follows ;--<br />
First ten years' growth 1 1/ 16".<br />
Third ten years' growth 2 6/ 8".<br />
Fifth ten years' growth 1 3/ 16".<br />
Last seven years' growth 6/ 8".<br />
Second ten years' growth 3 1/ 16"<br />
Fourth ten years' growth 2 1/ 16"<br />
Sixth ten years' growth 2"<br />
Total 67 years.<br />
So far as can be seen the only unusual item in the above analysis<br />
is the 2" growth in the sixth decade and this may have been due to<br />
some thinning factor. Stumps, old or new, are remarkable for their<br />
absence and this is further suggestive that the crop has stood in its<br />
present open state for some long time past.<br />
<strong>The</strong> following figures indicate well how fine a crop <strong>of</strong> trees is this<br />
Cedar at Glengarra. <strong>The</strong> mean Basal Area tree was found from<br />
measuring 30 trees in a line across the middle <strong>of</strong> the wood. <strong>The</strong><br />
number <strong>of</strong> stems per acre was found by averaging the number <strong>of</strong> stems<br />
per acre on two l / lOth acre squares located in the middle <strong>of</strong> the wood.<br />

Higher volume figures were obtained from a 1/10th acre plot<br />
measured at the same time and from a Census <strong>of</strong> Woodlands which<br />
was carried out a few years before, both <strong>of</strong> which showed a V.P.A.<br />
<strong>of</strong> well over 5,000 cubic feet. <strong>The</strong> V.P.A. figure <strong>of</strong> 4,762.8 may<br />
therefore be considered conservative.<br />
Comment.<br />
Comparison shows that this Cedar crop falls easily into first quality<br />
Scots Pine (Scotland) (B.F.C. Yield Tables) when judged by volume<br />
production, but it falls far short <strong>of</strong> first quality when judged properly<br />
on height growth according to age. When compared with European<br />
Larch it is found that on a basis <strong>of</strong> volume the Cedar falls into second<br />
quality class, but the contrast as to height growth is still more marked<br />
in this case, the Cedar falling below third quality class B.F.C. yield<br />
tables.<br />
This Cedar at Glengarra impresses one most as to the bulk <strong>of</strong> the<br />
individual tree in the stand and in the manner in which they hold<br />
their girths so well up to about 40'-this, apart from their apparent<br />
vigour and health. Having taken into consideration the retention <strong>of</strong><br />
dead branches for so long and to such a low level and the other<br />
factors enumerated above, not least the relation <strong>of</strong> height to volume,<br />
it seems not unlikely that the planting distance was greater than six<br />
feet in the first place, or that there was some species in mixture which<br />
failed, or that considerable failures were caused in the early stages<br />
by some damage being done to the young crop resulting in the trees<br />
being widely spaced for the greater part <strong>of</strong> their life.<br />
Seed.<br />
A fine crop <strong>of</strong> cones is borne on these Cedars in favourable years.<br />
Seed was extracted from twelve cones which were collected in the<br />
autumn <strong>of</strong> 1944. Thirty selected seeds were sown by the writer in<br />
the spring <strong>of</strong> 1945 from which three seedlings, two <strong>of</strong> which still<br />
survive, were obtc-ined. <strong>The</strong> remainder <strong>of</strong> the seed was sent to<br />
A vondale where a few more seedlings were obtained and the transplants<br />
are still to be found in the garden nursery there. It seems<br />
indicated that as many seed collections as possible should be made<br />
from these trees before they start to decline.<br />
Conclusion.<br />
<strong>The</strong>re seems to be one definite conclusion to draw from the foregoing<br />
observations: that the cultivation <strong>of</strong> Cedrus Deodara as a forest<br />
crop deserves much more <strong>of</strong> our attention than it has had in the past.

General Note on Species.<br />
<strong>The</strong> Deodara (Cedrus Deodara Loudon) is a native <strong>of</strong> the West<br />
Himalayas, extending westwards through Kashmir and on to<br />
Afghanistan. It is not generally found naturally in pure stands but is<br />
found in mixture with Picea morinda, Pinus excelsa and various oaks.<br />
Its maximum range <strong>of</strong> elevation is from 4,000' to 10,000' in its natural<br />
habitat but it is more usually confined to from 6,000' to 8,000'. It<br />
finds its region <strong>of</strong> optimum growth where the rainfall is between 40<br />
and 75 inches.<br />
A tree <strong>of</strong> 250 feet was recorded by Schlich in the Himalayas but<br />
these trees live to a great age in their own country, some standing<br />
trees being estimated to be 400 years old. Normal growth under these<br />
conditions is said to be 8 to 12 annual rings to the inch-which seems<br />
to indicate that growth here is faster but only sustained for a comparatively<br />
short period.<br />
<strong>The</strong> seed <strong>of</strong> Cedrus Deodara was introduced into Britain by leslie<br />
Melville in 1831. In 1841 seed was sown on a big scale and the<br />
plants were widely distributed throughout estates in Britain. Subsequently<br />
it was noted by many observers that trees suddenly failed<br />
in or about from 40 to 50 years and the species was said to be<br />
vulnerable to frost and the cold damp English climate. It appears<br />
from the context <strong>of</strong> these remarks that they applied to single park<br />
or avenue trees and very little information <strong>of</strong> solid stands seems to<br />
be available.<br />
A tree <strong>of</strong> 84' X 7' 2" girth was recorded by Pr<strong>of</strong>essor Henry at<br />
Fota, Co. Cork in 1904 and was later recorded by H . M. Fitzpatrick<br />
at 85' X 8' II" about 1928. Other fine trees recorded by Mr.<br />
Fitzpatrick were 76' X S' 9" at Carton (Co. Kildare) 79' X 12' at<br />
Headfort (Co. Meath). <strong>The</strong> best tree recorded in Britain in Henry<br />
and Elwes was 90' X 9' 1". Doubtless these dimensions have been<br />
far exceeded long since by more recent recordings.<br />
<strong>The</strong> timber <strong>of</strong> Deodara is said to be very durable when grown in<br />
its natural habitat. It is hard, oily and scented being used for building,<br />
sleepers, furniture and for many other purposes.<br />
Some doubt has been thrown on the quality <strong>of</strong> the timber when<br />
grown in the climate <strong>of</strong> these islands and it is said to be s<strong>of</strong>t and<br />
to lack durability.<br />

DOUGLAS FIR IN CO. WICKLOW<br />
By T. CLEAR, B.AGR.SC.<br />
THE "green" Douglas Fir (Pseudotsuga taxi folia) is a native <strong>of</strong> the<br />
Pacific coastal region <strong>of</strong> the United States and Canada. It grows<br />
best in the coastal region <strong>of</strong> Oregon, Washington and British Columbia,<br />
where the climate, and more particularly the rainfall, is very similar to<br />
that <strong>of</strong> the Wicklow mountains. European foresters came early to the<br />
recognition <strong>of</strong> its possibilities as a timber tree. Its remarkable growth<br />
in its native habitat and the high quality <strong>of</strong> its timber won for it a<br />
high reputation even among the coniferous giants <strong>of</strong> the "fog belt".<br />
It was introduced to Europe in 1827 but was not planted to any extent<br />
before 1850.<br />
Early plantings were as single specimen trees and small groups in<br />
Arboreta, on avenues and in selected spots in open woodland. <strong>The</strong><br />
results <strong>of</strong> this type <strong>of</strong> planting are to be seen in many parts <strong>of</strong> Ireland,<br />
particularly in demesnes like Powerscourt, Carton, etc.<br />
<strong>The</strong> growth <strong>of</strong> the specimens thus planted at Kilruddery was most<br />
remarkable and by the beginning <strong>of</strong> the present century Douglas Fir<br />
was 'Well on the way to becoming a firm favourite in the race for pride<br />
<strong>of</strong> place among the newer exotics. After seeing the giants at<br />
Powers court and Carton one can well understand the superoptimism<br />
that prevailed with regard to this species some 40 or SO years ago.<br />
Its extensive use as a forest tree coincided with the advent <strong>of</strong> State<br />
Forestry in Ireland. Much <strong>of</strong> its early planting was on old woodland<br />
sites as at Dundrum, Avondale, Camolin and was usually in mixture<br />
with larch or spruce. On private estates it was used as a filler in<br />
sparsely stocked hardwood areas, and with Abies grandis, Thuja plicata,<br />
Picea sitchensis and other <strong>of</strong> its natural associates began to give a<br />
new look to many demesne woodlands. A most remarkable example<br />
<strong>of</strong> this type <strong>of</strong> planting is to be seen at Carton and deserves the closest<br />
study by our silviculturists.<br />
With the advent <strong>of</strong> the 1914/18 war planting practically ceased<br />
and was not renewed on any appreciable scale until 1921. <strong>The</strong> post<br />
war plantings differed in many respects from the pre-war efforts. Large<br />
areas <strong>of</strong> sheep mountain and cleared woodland, particularly in Co.<br />
Wicklow, were acquired and extensive monocultures <strong>of</strong> Douglas Fir,<br />
Sitka Spruce and other promising exotics began to make their appearance.<br />
<strong>The</strong> green Douglas Fir was used extensively in those early postwar<br />
plantings, and figured largely in the selections as at Roddenagh<br />
in Aughrim (Planted 1921-1926); at Ballyboy in Glenmalure; and at<br />
Crone and Ballyreagh in Glencree.<br />
<strong>The</strong> site requirements <strong>of</strong> Douglas Fir were early recognised and<br />
moderately deep, light well-drained soils containing ample moisture<br />
and which were fairly well sheltered were selected for this species.<br />
<strong>The</strong>se site conditions were prevalent in the early acquisitions in<br />
Co. Wicklow and in south-east Ireland generally and are asso-
ciated with lower Silurian, mICa schist and the better old red<br />
sandstone rocks. Heavy bracken on bare land and a variety <strong>of</strong> ferns<br />
in old woodland were considered indicators <strong>of</strong> good Douglas ground.<br />
With the advent <strong>of</strong> more extensive planting programmes attention to<br />
the site requirements became less rigid and Douglas Fir was planted<br />
at higher elevations on exposed light "grass heath" sites where furze<br />
(Ulex europaeus and Ulex galii) and heather (Calluna vulgaris) were<br />
all too prone to become dominant when the ground was enclosed<br />
against stock. It was planted also on lowland limestone areas where<br />
frost was an important factor as was also the heavy growth <strong>of</strong> aggressive<br />
meadow grasses such as Cocks foot.<br />
This departure from sound selection <strong>of</strong> sites could have but one<br />
result-poor crops. <strong>The</strong>se "ecological errors" were so numerous, however,<br />
that Douglas Fir came to be regarded as an unreliable species<br />
and quickly lost in popularity. <strong>The</strong> promised heavy yields did not<br />
materialise. <strong>The</strong> species was prone to flatter but to deceive-starting<br />
vigorously enough but checking in the thicket stage and producing an<br />
unwanted quota <strong>of</strong> wolves-with a pronounced sweep in the butts and<br />
very aggressive side branches. <strong>The</strong> advent <strong>of</strong> the insect Chermes<br />
Cooleyii and the leaf-cast fungus (Phaecocryptopus Gaumanii), and<br />
the frequent reports <strong>of</strong> extensive wind throw and snow break added<br />
to the general uncertainty. Adding to the long list <strong>of</strong> troubles associated<br />
with this species, the blue or Colorado Douglas Fir, a very inferior tree,<br />
was sometimes planted in mistake for the Vancouver variety. Small<br />
wonder then that Douglas Fir fell from its relatively important position<br />
among forest tree species to one <strong>of</strong> minor importance in <strong>Irish</strong> Forestry<br />
and disappeared almost completely from State nurseries. <strong>The</strong> reaction<br />
went further and a policy <strong>of</strong> replacement <strong>of</strong> unsatisfactory stands <strong>of</strong><br />
Douglas Fir became the order <strong>of</strong> the day.<br />
During the war the unprecedented demand for fuel enabled<br />
foresters to carry out extensive improvement cuttings <strong>of</strong> crooked and<br />
coarse dominants in young 15-20 year old stands. This work has done<br />
much to rehabilitate the Douglas Fir in County Wicklow and the great<br />
improvement apparent in these stands has led to a revival <strong>of</strong> interest<br />
in the species.<br />
In 1948 I undertook the survey and assessment <strong>of</strong> growing stock<br />
in Roddenagh property <strong>of</strong> Aughrim forest. <strong>The</strong> area was intensively<br />
sampled using the line-plot method with 1/ 10th acre plots falling<br />
every 4 chains. This method <strong>of</strong> sampling provides growth statistics<br />
which could be analysed to provide information on site quality as<br />
affected by elevation and other site factors. Numerous sample trees<br />
were felled and stem analyses carried out.<br />
In Aughrim Forest Douglas Fir figures largely in the earlier plantings.<br />
In Roddenagh and Killaduff (the properties assessed) there are<br />
over 300 acres <strong>of</strong> pure Douglas Fir aged 22-27 years covering a wide<br />
range <strong>of</strong> site qualities.

<strong>The</strong> area planted with Douglas Fir lies between the 450' and 900'<br />
contours on Roddenagh hill- and between 300' and 400' in Killaduff<br />
north. <strong>The</strong> soil is a relatively light shaley loam <strong>of</strong> Silurian origin only<br />
slightly podsolized, fairly deep at lower levels, but becoming<br />
shallower and lighter and more podsolized with increased . elevation.<br />
Compartments 2-11 face south to south-east and are fully exposed. <strong>The</strong><br />
contours are convex and the site could be described as a bold dry<br />
exposed ridge which is an outlier <strong>of</strong> the Wicklow range with little or<br />
no shelter from higher ground to the south.<br />
Compartments 15, 18, 19, 23, 26, 30, 34, 35, 38, 39, 40, 43, 44,<br />
45 face north-east to north and are fairly sheltered with the concave<br />
outline <strong>of</strong> the map contours indicating better moisture conditions, as<br />
also does the occurrence <strong>of</strong> springs and a patch <strong>of</strong> seepage in Compt.<br />
38. Planting <strong>of</strong> Douglas Fir was taken up to 900 feet on this sheltered<br />
side. <strong>The</strong>re are no records <strong>of</strong> the native vegetation <strong>of</strong> the site before<br />
planting but <strong>Irish</strong> furze seems to have dominated the dry S.E. ridge<br />
(C. 2, 3, 5, 6, 7, 8, 9, 10, 11). Bracken occurred on the moister and<br />
more sheltered notherly slope and grassheath vegetation was general<br />
above 800'.<br />
Planting commenced in the season 1921-22 and was carefully supervised<br />
and thoroughly done. <strong>The</strong> planting stock was (2- 1- 1) 4 years<br />
old transplants and the spacing was 6' X 6'. Growth was rapid from<br />
the start as judged by a stem analysis <strong>of</strong> average dominants. Ring<br />
width was about 4 rings to the inch up to 1930 when there is striking<br />
evidence <strong>of</strong> check in some parts <strong>of</strong> the plantation. For 3 or 4 years<br />
rings <strong>of</strong> 1/ 16" occurred followed by an improvement to 1/ 8" which<br />
was maintained up to 1937 when a further check occurred giving rings<br />
<strong>of</strong> 1/ 32" for 3 years. This check was general over the whole area <strong>of</strong><br />
Roddenagh Hill. <strong>The</strong>re was an improvement in 1940 to 1/ 16" which<br />
increased to 1/ 8" in 1942 and to 3/16" in 1944. <strong>The</strong>n growth fell <strong>of</strong>f<br />
gradually until in 1947 ring width was again 1/ 16". This succession<br />
<strong>of</strong> check followed by release is even more striking on the co-dominants<br />
while the sub-dominants have been in full check since about 1940.<br />
<strong>The</strong> first check appears to have been caused by excessive competition<br />
from furze the cleaning <strong>of</strong> which was neglected for some years. This<br />
check was most pronounced on dry ridges and at the higher elevations.<br />
A heavy cleaning carried out in 1933 or 1934 was in the nature <strong>of</strong> a<br />
thinning in its silvicultural affect-many trees had been suppressed<br />
and the furze was well up into the canopy according to the <strong>of</strong>ficers-incharge<br />
at the time. <strong>The</strong> second check in 1937 could be accounted for<br />
as being normal and due to root competition indicating that thinning<br />
should have been carried out in 1935 or 1936 i.e. 13 or 14 years after<br />
planting. <strong>The</strong> check was so severe, however, that one is inclined to the<br />
belief that leaf shedding must also have been excessive about this<br />
time. Stands <strong>of</strong> Douglas Fir about 15 to 18 years old are <strong>of</strong>ten condemned<br />
because <strong>of</strong> general stagnation by excessive loss <strong>of</strong> foliage. It
L2<br />
is interesting to observe that this condition prevailed in Aughrim for<br />
some years. <strong>The</strong> general improvement which set in in 1939 or 1940<br />
coincided with brashing operations as evidence <strong>of</strong> the sawn branch stubs<br />
reveals. <strong>The</strong> assessors attributed the improved growth to a thinning<br />
which was presumed to have occurred about this time. However, there<br />
was no record <strong>of</strong> a thinning having been carried out in 1939 and the<br />
<strong>of</strong>ficers in charge state that the stands only received a brashing. It<br />
appears, therefore, that brashing has given a pronounced stimulus to<br />
the crop. I am convinced that the mulching effect <strong>of</strong> the branch litter<br />
so improved the moisture conditions as to <strong>of</strong>fset the effects <strong>of</strong> root<br />
competition and disease. <strong>The</strong> improvement in increment got a further<br />
boost in 1942 when a thinning <strong>of</strong> dominants was carried out.<br />
<strong>The</strong> crop is now vigorous and healthy and with thinning, increment<br />
can be satisfactorily maintained. <strong>The</strong> trees have doubled in timber<br />
volume in the last 5 years. Extensive growth studies reveal annual<br />
increments varying from 8'10 to 15%. For example in Compartment<br />
3 the average dominant increased from 3.62 cu. ft. (U.B.) true volume<br />
to 6.07 cu. ft. (U.B.) true volume and the average co-dominant<br />
increased from 1.6 cu. ft. to 2.9 cu. ft. over 5 years.<br />
In compartment 4 the average dominant increased from 5.5 cu. ft.<br />
to 7.10 cu. ft. and the co-dominant or sub-dominant from 1.28 to<br />
1. 62 cu. ft. in five years.<br />
Compartment 3 seems to have been cleaned and thinned earlier<br />
than C4 since the early (1930) check is not in evidence and the<br />
stocking is now lower. This as well as the fact that C3 enjoys a lower<br />
elevation, accounts for the better current increment.<br />
<strong>The</strong> following statistics are based on an analysis <strong>of</strong> 34 plots <strong>of</strong><br />
1/10th acre covering the south-eastern end <strong>of</strong> Roddenagh Hill<br />
(C2-11). In all cases calculations for Mean Annual Increment include<br />

In Compartment 10 and 11 (700'- 800') the Douglas Fir has<br />
largely failed. <strong>The</strong> better remnants <strong>of</strong> the stand remain and the yields<br />
<strong>of</strong> 800 to 850 cu. ft. per acre after 27 years (30 cu. ft. M.A.I.) speak<br />
for themselves. <strong>The</strong>se Compartments have been beaten up with J.L.<br />
which promises very well on this site.
14<br />
Compartments 15, 18 19 and 23 are somewhat better sheltered than<br />
Compartments 2-11 but the elevation is 650'-800'. <strong>The</strong> contours<br />
indicate excessive drainage and drought is likely to be an important<br />
factor. <strong>Irish</strong> furze played an important role here in checking growth<br />
especially in Compartment 23, where partial failure has resulted,<br />
necessitating replanting with Japanese Larch.<br />
<strong>The</strong> "dry ridge" is a most unsuitable site for Douglas Fir and<br />
competition from native vegetation is excessive on such sites. Nevertheless<br />
Douglas Fir has not done too badly as can be seen by the<br />
following results to date.<br />

Conditions in Compartments 34, 35, 38, 39, 40, 43, 44, 45 are<br />
much more favourable. As can be seen by the contour lines this portion<br />
<strong>of</strong> the area is "cupped" and sheltered (the concave contours indicating<br />
better moisture conditions and shelter) with better soil depth. <strong>The</strong><br />
native vegetation was likely to have been bracken rather than furze.<br />
<strong>The</strong> improvement in rate <strong>of</strong> growth is quite remarkable considering<br />
the stand here is 3 years younger.<br />

<strong>The</strong>se last three Compartments are on the edge <strong>of</strong> the plantation<br />
and subject to exposure.<br />
In KILLADUFF NORTH the Douglas lies between 350' and 500'<br />
and while the area is sheltered the ground is rocky and the soil rather<br />
shallow in places.<br />
Growth has been very satisfactory as can be seen by the M.A.!.<br />
figures.<br />
This area was only 22 years planted on the date <strong>of</strong> assessment and<br />
as one would expect, the current annual increment is very much higher<br />
than the Mean.

In this property Douglas Fir has failed on the wet flats- which<br />
adjoin the river. <strong>The</strong>re seepage areas were water-logged and carried<br />
molinia and tufted Aira grasses before planting.<br />
Douglas fir in mixture.<br />
In Roddenagh Wood-an area very similar to the Killaduff North<br />
property-namely old woodland-350-450' elevation fully sheltered,<br />
with the soil moderately deep and moist and free rooting- Douglas Fir<br />
was planted in mixture with Japanese Larch 50% <strong>of</strong> each at 6' X 6'.<br />
<strong>The</strong> Douglas has been practically eliminated by suppression and the<br />
remnant can be maintained only by the deliberate sacrifice <strong>of</strong> the more<br />
vigorous Japanese Larch.<br />

<strong>The</strong>re were many sub-dominant Douglas Fir-with heights around<br />

It is still possible in this stand to produce . a final crop largely<br />
composed <strong>of</strong> Douglas Fir but it involves a sacrifice <strong>of</strong> the main increment<br />
producer-the Japanese Larch. On the point <strong>of</strong> quality <strong>of</strong> final<br />
produce there is much to recommend a pro-Douglas Fir policy. In this<br />
connection the following experience may be <strong>of</strong> some interest. <strong>The</strong><br />
freshly cut samples taken for stem analyses (discs 2" thick cut <strong>of</strong>f at<br />
5', 15' etc.) were stored in sacks for some days before being collected<br />
for examination. When examined the Japanese Larch sections were<br />
found to be covered with a dense mat <strong>of</strong> fungus mycelium and the<br />
wood was deeply stained and almost black in colour right through.<br />
<strong>The</strong> Douglas Fir showed little or no trace <strong>of</strong> discoloration and were<br />
as bright and clear as when cut.<br />
CONCLUSIONS.<br />
<strong>The</strong> main conclusions that one is tempted to draw from the results<br />
<strong>of</strong> this assessment might be listed as follows:<br />
(a) Douglas Fir even under fairly suitable conditions is not likely<br />
to be a very heavy yielder on the foothills <strong>of</strong> County Wicklow.<br />
(b) It is, however, much superior in growth rate to the normal<br />
alternative selections, European Larch and Scots Pine.<br />
(c) It is inferior in height growth to Japanese Larch in the early<br />
stages, at least, but promises to give a much better quality<br />
timber: further the evidence from stem analysis would<br />
indicate that while the Douglas Fir increment is well maintained<br />
between the 20 and 30 years that <strong>of</strong> Japanese Larch<br />
tends to fall <strong>of</strong>f.<br />
(d) Douglas Fir is extremely sensitive to drought and to root<br />
competition. An aggressive vegetation like Ulex Gallii on<br />
dry exposed sites can bring the crop into complete check.<br />
This condition is aggravated by the disease Phaecocryptopus<br />
Gaumanii which delays canopy formation.<br />
(e) Douglas Fir shows good powers <strong>of</strong> recoverey from disease<br />
and check, and is much superior to Scots Pine in this respect.<br />
(f) <strong>The</strong>re are indications that the cleaning <strong>of</strong> furze and other<br />
competitive vegetation must on no account be neglected.<br />
(g) <strong>The</strong> brashing <strong>of</strong> the crop appears to have a most invigorating<br />
effect and at a critical stage, and this may help to put this<br />
operation in a new and more favourable light.<br />
(h) Early thinning (starting at the 15th year after planting) and<br />
the reduction <strong>of</strong> numbers to between 400-500 stems by the<br />
25th year seems to be very necessary if increment is to be<br />
maintained.<br />
(i) <strong>The</strong> fact that co-dominates and sub-dominants show very<br />
little response to crown thinning would seem to indicate that<br />
a heavy low thinning might be more suitable than crown<br />
thinning.
18<br />
Since carrying out this survey at Aughrim, further assessments have<br />
been concluded at Glenmalure in central Co. Wicklow and at Glencree<br />
in North Central Wicklow in 20 to 30 years old stands and at<br />
Kilruddery (near Bray) in 30-40 years old stands.<br />
<strong>The</strong> results have helped to confirm the general impression chat<br />
Douglas Fir in heavily thinned stands improves enormously between<br />
the 20th and 40th year: that it gives promise <strong>of</strong> good yields<br />
on sites up to 700' on northern slopes especially on deep loamy soils:<br />
and that it appears to throw <strong>of</strong>f the effects <strong>of</strong> Phaecocryptopus Gaumanii<br />
and to enter into a period <strong>of</strong> very vigorous growth, after heavy<br />
thinning.<br />
Final yields may be very much heavier at Aughrim and other centres<br />
in Wicklow than present returns iedicate. <strong>The</strong> very serious check which<br />
was experienced between the 10th and the 20th year did much to<br />
depress yields and comparison with British Forestry Commission yield<br />
tables would be likely to show that Wicklow stands in a very unfavourable<br />
light. It is interesting to note, however, that American and<br />
Continental tables for Douglas Fir give yields comparable with those<br />
recorded here.<br />

NURSERY MECHANIZATION<br />
By M. E. McNULTY.<br />
NURSERY foresters are continually worried about costs and<br />
endeavour to tryout new ideas to keep them at a low level,<br />
whilst at the same time ensuring that the full annual programme is<br />
completed.<br />
This controlling <strong>of</strong> costs is not at all easy when one remembers<br />
that present day wages and overheads are approximately three times<br />
the pre-war figure, while at the same time it cannot be said that the<br />
output by the Nursery Staff has kept pace with the increased<br />
expenditure.<br />
To keep costs, therefore, within the limits <strong>of</strong> proper nursery<br />
economics, it is essential that manual effort be supplemented by as<br />
much mechanization as possible.<br />
Nursery foresters may be interested in our efforts at Tair Onen,<br />
towards that end, for the past few years.<br />
Tair Onen Nursery was started in 1936 and may now be considered<br />
in the established category with all its attendant ills-over-production<br />
due to necessity in its early years with consequent lowering <strong>of</strong> natural<br />
fertility and high incidence <strong>of</strong> weed attack.<br />
Our main worry was the high cost <strong>of</strong> weeding broadcast seed beds<br />
which reached its peak in 1946. As well as the cost <strong>of</strong> weeding, at<br />
least 10'10 <strong>of</strong> the first year's seedlings were lost mainly through faulty<br />
weeding by inexeprienced labour. When one considers that our<br />
weeding areas in an average year amount to about 60 acres including<br />
lines and seedbeds, one may appreciate our problem.<br />
To meet the situation, the "Macslat" Multiple Seedsowing Drill<br />
'."'1as evolved. It is worked on the endless belt system with a density<br />
control, sows eight drills longitudinally, the drills being 4 inches apart.<br />
<strong>The</strong> machine opens the drills, sows the seed and covers with grit in<br />
one operation, though the grit covering part requires further development.<br />
<strong>The</strong> 1946 model had a wooden hopper mounted on tyre-Iess cycle<br />
wheels, the endless belts being provided from an old inner tube <strong>of</strong> a<br />
lorry. <strong>The</strong> principle <strong>of</strong> its working was satisfactory.<br />
<strong>The</strong> 1948 model is an improvement on our first effort. It is a<br />
compact, all-steel unit mounted on pneumatic tyred wheels, having<br />
its endless belt specially made. <strong>The</strong> machine at present is manually<br />
operated. It is visualized that a later model may be power driven with<br />
other refinements. <strong>The</strong> present machine cost approximately £55.<br />
<strong>The</strong>oretically, drills take up three times the area <strong>of</strong> broadcasting, but<br />
in this instance, it was decided to drill at broadcasting density; species<br />
coming out as 1 + 0 would not hurt, whilst those remaining in for<br />
two years had a proportion pricked out at the end <strong>of</strong> the first year<br />
and bedded out leaving a number in for two years correspondine to<br />
that <strong>of</strong> drilling density.

In practice the following comparisons stood out this year. 4 lb.<br />

General Observations.<br />
Manual weeding <strong>of</strong> drilled beds is only one-fifth that <strong>of</strong> broadcast.<br />
Hoeing can be carried out on the other 4/ 5. A seven-pronged two-inch<br />
spud multiple hoe was evolved complementary to the seed sowing<br />
machine. Two men hoe eight drills simultaneously and cover 2,400<br />
sq. yards in one day.<br />
It was noticed that seedlings in drills grew to a greater height the<br />
first year than those in broadcast beds. <strong>The</strong> constant hoeing gives<br />
better moisture retention. It is not suggested that drilling is necessary<br />
for all nurseries. Obviously in newly-started nurseries where there is<br />
no weed growth for the first few seasons, broadcasting is easier.<br />
Readers <strong>of</strong> the Quarterly Journal <strong>of</strong> the Royal Forestry <strong>Society</strong> <strong>of</strong><br />
England and Wales will have noticed an article in the October 1949<br />
issue by Mr. W. E. Hiley on his observations on Nursery Machinery<br />
and Methods, from a recent visit to Western American Nurseries. He<br />
describes similar machines as those developed at Tair Onen for drill<br />
sowing <strong>of</strong> seed, except that the American product is tractor pulled.<br />
It shows that other up-to-date countries are fully alive to the<br />
potentialities <strong>of</strong> Nursery Mechanization as a contribution to lower costs.
THE PLACE OF FORESTRY IN THE<br />
NATIONAL LIFE<br />
(Report <strong>of</strong> symposium held on the occasion <strong>of</strong> the Ninth Annual<br />
General Meeting <strong>of</strong> the <strong>Society</strong> <strong>of</strong> <strong>Irish</strong> <strong>Foresters</strong>).<br />
Mr. Mooney.<br />
MR. MOONEY, forestry <strong>of</strong>ficer, was the first speaker and mooted<br />
the idea <strong>of</strong> the communal forest. We had seen, he said, over the<br />
past few years a great revival <strong>of</strong> interest in afforestation in this country.<br />
At the top level we had the announced policy <strong>of</strong> the Government to<br />
step up the annual planting programme to 25,000 acres with an<br />
ultimate target <strong>of</strong> over one million acres <strong>of</strong> plantations. As well as<br />
our own <strong>Society</strong> we had such groups as the Trees for Ireland Committee,<br />
the Roadside Tree Association, mAl,CpAl, nAl, felpme and others<br />
all doing their share in encouraging tree-planting. <strong>The</strong> newspapers too<br />
had given forestry more than its usual share <strong>of</strong> publicity, and had,<br />
without exception, supported and recommended to their readers the<br />
great idea <strong>of</strong> forestry and urged its adoption on a far greater scale<br />
than at present.<br />
Encouraged by this awakening <strong>of</strong> interest, he was going to suggest<br />
yet another means <strong>of</strong> getting trees planted. <strong>The</strong> idea he was about to<br />
<strong>of</strong>fer, the communal forest, was by no means a new one and has been<br />
well known in Europe for hundreds <strong>of</strong> years. It is the forest that is<br />
owned by the commune or local administrative body as distinct from<br />
either the State-owned or privately-owned forest. Before the last war<br />
Germany had 4,857,500 acres <strong>of</strong> such forest, which represents 15.5%<br />
<strong>of</strong> her total forest area. In France too, the communal forest is a strong<br />
part <strong>of</strong> the forestry system and in most European countries the communal<br />
forest system exists. <strong>The</strong> usual area <strong>of</strong> these forests ranges from<br />
200 to 1,300 acres and they are managed by qualified foresters generally<br />
under the 'remote control' <strong>of</strong> the State forest service.<br />
We have all seen, he said, in our wanderings through the country<br />
the rocky valley with its steep slopes covered with bracken and gorse,<br />
the old woodland site now a tangled mass <strong>of</strong> briar and thicket scrub<br />
vegetation, the higher heather-clad slopes~all productive forest lands<br />
but at present not contributing one penny to the country's economy and<br />
seemingly fated to remain in untouched unproductivity to the end <strong>of</strong><br />
time. <strong>The</strong>se small areas <strong>of</strong> waste ground which vary from one to<br />
fifty acres in extent are general and will be found scattered over every<br />
county but they are particularly noticeable in Wicklow, Tipperary, Cork,<br />
Kerry, Clare and Donegal. <strong>The</strong>y can rarely be handled by the State<br />
forestry service, being too small and scattered for economic management<br />
by a service constituted to deal with blocks <strong>of</strong> thousands <strong>of</strong> acres.<br />
<strong>The</strong> farmers on whose holdings they occur may sometimes have the<br />
urge to plant them but lack the means to do so. Generally, however,<br />
both the urge to plant and the means to do so are lacking. Consequently

(iii) <strong>The</strong> powers <strong>of</strong> County Councils under the Agricultural Act<br />
<strong>of</strong> 1931 are more closely allied to forestry <strong>of</strong> a commercial or semicommercial<br />
nature. Under this Act the County Council is required to<br />
provide a minimum sum out <strong>of</strong> its rates [at least two pence in the<br />
pound] to its County Committee <strong>of</strong> Agriculture to be applied to its<br />
agricultural and allied schemes in addition the Council may strike a<br />
special rate <strong>of</strong> -td. in the £ reserved particularly to forestry. Much good<br />
work has been done under this Act but the schemes have all aimed at<br />
aiding the individual to help himself and this aid has had to be<br />
restricted so that the limited sum available could be made to meet the<br />
needs <strong>of</strong> all who wished to avail <strong>of</strong> the scheme. <strong>The</strong> County Committee<br />
<strong>of</strong> Agriculture is a body principally concerned with technical<br />
advice and it has not either the resources or the powers to undertake<br />
the work itself. Its efforts at encouraging afforestation are usually<br />
confined to the provision <strong>of</strong> a limited number <strong>of</strong> transplants at reduced<br />
prices.<br />
Local authorities also provide scholarships which can be availed <strong>of</strong><br />
in forestry at the National University but that so few avail <strong>of</strong> them for<br />
this subject shows the need for education in both national and<br />
secondary schools <strong>of</strong> necessity for and importance <strong>of</strong> afforestation.<br />
<strong>The</strong> combined contribution <strong>of</strong> Local Bodies to forestry under the<br />
above heads seldom cost more than one or at most two pence in the £<br />
on the Rates but a scheme as envisaged by Mr. Mooney would cost up<br />
to 1/ - in the £. This he said was not to be taken as a criticism <strong>of</strong><br />
Mr. Mooney's proposals but rather to show that they represented a<br />
fundamental departure from present practice and a bold solution for<br />
an important national problem, the planting <strong>of</strong> relatively small pieces<br />
<strong>of</strong> lands unsuited for other purposes. <strong>The</strong> scheme had the further<br />
merit-and in this it was almost unique in proposals normally made to<br />
Local Authorities-in that all expenditure would in a short time yield<br />
a substantial income and return for the capital invested, not merely in<br />
shelter or amenity or other intangible form, but in hard cash.<br />
That a scheme such as that envisaged by Mr. Mooney was not<br />
beyond the scope or capabilities <strong>of</strong> Local Authorities is adequately<br />
illustrated by the success they have achieved in such diverse schemes<br />
as housing, turf production, drainage, road making, etc. It was<br />
impossible at the moment to forsee and discuss in detail all the difficulties<br />
likely to arise and the many questions raised by the proposal<br />
but he thought that as a scheme it undoubtedly was worthy <strong>of</strong> very<br />
serious consideration and publicity.<br />
In the past two years, he said, some £2,000,000 had been spent on<br />
minor drainage schemes and we should remember that the American<br />
money so used was repayable over 3S years at 2-t% interest. If we<br />
could afford such expenditure then the sum <strong>of</strong> £16,000 per county on<br />
a forestry scheme seemed quite feasable, but public opinion would have<br />
to make the decision. He felt, however, that any approach to grant the
25<br />
necessary powers to spend their own money on establishing their own<br />
forests would be welcomed by local authorities.<br />
He suggested that a forestry scheme could be run in conjunction<br />
with drainage schemes, while the nursery problem might be tackled<br />
by the Vocational Schools. It would be necessary however, to educate<br />
and foster a spirit <strong>of</strong> forest consciousness in the public before such a<br />
scheme could hope to succeed.<br />
Mr. Litton.<br />
<strong>The</strong> next speaker, Mr. Litton, gave his views as a farmer on the<br />
position <strong>of</strong> forestry in the national life. Farming and trees, he said,<br />
had much in common, but he would not agree with forestry experts<br />
dictating to the farmer, who really knew his own business best. He<br />
had seen a slogan that the "onus <strong>of</strong> tree planting lies with the farmer"<br />
but he did not take that seriously as he believed it was put out by<br />
nurserymen. He had also heard that trees would improve the climate<br />
but he considered that the climate did not need improving: we had,<br />
he thought, one <strong>of</strong> the best climates in the world. Again he had heard<br />
that trees beautify the countryside and induce more tourists to come<br />
here, but this he called a fantastic idea. If it was going to draw more<br />
tourists he certainly did not want it. <strong>The</strong>re was nothing more distressing<br />
to him than gates left open, crops ruined, and plantations burned<br />
by careless tourists brought here because we had beautified the countryside.<br />
Trees for shelter were, he said, the farmer's own business and<br />
the farmer was the best judge <strong>of</strong> whether such shelter was necessary<br />
and where to put it.<br />
From the farmer's point <strong>of</strong> view, if forestry was going to take a<br />
place in the national life it must be as a commercial proposition. He<br />
thought Mr. Mooney's scheme was most undesirable. It was suggested<br />
it would cost up to 1/- in the £ on the rates and this would put the<br />
farmer out <strong>of</strong> business. Farmers already paid a heavier tax than anyone<br />
else and he considered it would be unjust to increase the rates by 1/<br />
in the £ for forestry purposes.<br />
If you want to get the farmer interested he said you must show by<br />
more than mere figures that it will pay-figures do not cut much ice<br />
with the farmer, he will move very slowly which is really the best and<br />
only way. He was not himself convinced that the proposed scheme was<br />
a paying proposition.<br />
We all want to see more trees to improve the country, he said,<br />
and in the national outlook it might be far better to have more trees<br />
on the marginal lands. In mountain farms they graze a few sheep or<br />
cattle on these lands and while the output is very low the forester says<br />
trees would pay better, you cannot convert the value <strong>of</strong> this land to<br />
the farmer in hard cash, it must be taken in relation to the whole<br />
farm. If you take this land away you upset his economy so you simply<br />
can't take it away-if he loses this high ground his farm goes 'flop'.
<strong>The</strong> acquisition <strong>of</strong> the rough hill grazing for forestry will need an<br />
alteration in our system <strong>of</strong> husbandry and that will need research,<br />
research in the breeding <strong>of</strong> stock, in farm management, in land utilization,<br />
in forestry and the re-education <strong>of</strong> the farmer in the new system.<br />
Farming and forestry, he said, must go hand in hand and he considered<br />
that the ideal solution lay not in Local Administration but in<br />
attaching the forest to the farm under the farmer, with some Government<br />
controls and a Government-sponsored company to deal with<br />
utilization.<br />
Mr. FitzPatrick.<br />
Mr. FitzPatrick, who possessed the dual qualification <strong>of</strong> both<br />
farmer and forestry expert, dealt with the economic aspect <strong>of</strong> forestry<br />
in the national life. It was most important he said to grow just what<br />
we needed otherwise we would have a surplus <strong>of</strong> one class <strong>of</strong> material<br />
and a difficiency <strong>of</strong> another. Our former target <strong>of</strong> 600,000 acres <strong>of</strong><br />
plantations was, he understood, based on our consumption <strong>of</strong> timber<br />
and timber products for the year 1932-33. This was a curious year<br />
on which to base our figures as it was a year <strong>of</strong> depression and our<br />
present target <strong>of</strong> 1,000,000 acres seems much nearer the mark.<br />
<strong>The</strong>re were, he said, 300,000 farms and 400,000 rural dwellings<br />
in the country and these would need 10,000,000 stakes and 1,200,000<br />
wooden gates. <strong>The</strong>se could be made to last longer by chemical<br />
preservatives but even then they will not last for ever and constant<br />
replacements are necessary. Proper preservation <strong>of</strong> such materials was<br />
as good as growing extra timber, but unfortunately there was no firm<br />
in Ireland at present to supply preserved timber to the farmer. Besides<br />
this the farmers' homes and out <strong>of</strong>fices would need timber for repairs<br />
and renovations and this would take a further 2,400,000 cu. ft. <strong>of</strong><br />
timber annually. To meet these needs and from his own experience<br />
as a farmer he was convinced that trees were absolutely invaluable on<br />
the farm.<br />
Almost every farm, he thought, had a bit <strong>of</strong> waste ground which<br />
could be planted and most farmers had the spare time to do the planting.<br />
Unfortunately they were accustomed to crops ripening in 5 to 6<br />
months and the shift to a ripening period <strong>of</strong> 30 to 50 years was a big<br />
jerk to them. Fencing, particularly rabbit fencing, was another bugbear,<br />
and an expensive one.<br />
While he knew from experience that it was difficult to grow trees<br />
on the farm, it was by no means impossible. <strong>The</strong> main thing, <strong>of</strong> course,<br />
was to grow the type <strong>of</strong> material required. <strong>The</strong>re was a growing<br />
demand for small-sized stuff for stakes and fencing materials and for<br />
processing into pulp and fibre, etc. Rural electrification would take<br />
one-and-a-half million transmission poles and these again would<br />
require constant replacements. Pinus contorta had been found suitable<br />
for transmission poles in America and he would suggest that P.e. might
27<br />
be planted on better land than was customary at present, for a quick<br />
return.<br />
One <strong>of</strong> the merits <strong>of</strong> Mr. Mooney's scheme was the provision <strong>of</strong><br />
a constant and assured supply <strong>of</strong> timber for small local industries. At<br />
present it was possible for an outside firm or individual to buy up an<br />
entire wood and so deprive the small local industry <strong>of</strong> its raw material.<br />
When a wood is cut down and exploited it is gone for ever for that<br />
generation. <strong>The</strong> small industry while dependent on the local wood<br />
seldom had the capital to buy it outright and preserve it for their own<br />
needs.<br />
<strong>The</strong> speaker said he favoured Mr. Mooney's scheme and he thought<br />
farmers would do their part if encouraged. <strong>The</strong> whole question <strong>of</strong><br />
species to plant, and size <strong>of</strong> materials to produce would need expert<br />
examination and the farmer would need constant advice on what to<br />
plant, when to fell, the best way t1 market the produce. He envisaged<br />
a scheme with a forestry expert in every county who in addition to<br />
looking after the County Council forestry scheme would advise parish<br />
councils and individual farmers on all matter pertaining to forestry.<br />
A general debate followed to which the following members<br />
contributed :<br />
Mr. T. McCarty, who said that from his experience the farmers<br />
had very little interest in forestry and even this little was only maintained<br />
for a short time. He got his plants at approximately half market<br />
price from the County Council and he also got a grant from the<br />
Government for planting but he neglected after-care needed to produce<br />
good plantations. He agreed with the County Council forestry scheme<br />
as practised at present in Kildare (for which County he was forester)<br />
and gave figures to show it was a sound commercial proposition. He<br />
suggested that a start could be made on a smaller scale than that proposed<br />
by Mr. Mooney and said it would not cost anything like 1/ - in<br />
the £ on the rates. At present, he said, the rates paid for our agricultural,<br />
our horticultural and our poultry schemes so why not for our<br />
forestry scheme as well<br />
Mr. Galvin said that the Kildare scheme was not worked on the<br />
lines <strong>of</strong> Mr. Mooney's proposal. He pointed out that land tenure on<br />
the Continent was different to here and he thought that pride <strong>of</strong><br />
ownership would be a big obstacle to communal forestry here.<br />
Forestry, he said, was a highly technical and extremely critical<br />
science and outside the scope <strong>of</strong> County Councils and County Managers<br />
who were in any event already overburdened. He also thought that the<br />
present County Council schemes were adequate if fully availed <strong>of</strong>.<br />
He would not agree with Vocational Schools handling the forest<br />
nurseries as nursery technique requires more skill and attention than<br />
Vocational Schools could give it and he thought the nurseries could<br />
safely be left to private enterprise.
28<br />
Mr. Mangan said there was a lack <strong>of</strong> pioneer spirit among<br />
farmers. We had yet to sell the idea <strong>of</strong> forestry to the farmer and<br />
while it was going to be difficult it was not impossible. <strong>The</strong> E.S.B.<br />
rural electrification scheme had made a provisional estimate <strong>of</strong> one<br />
million transmission poles for their requirements over the first ten<br />
years, but in actual fact they had only used between 40,000 and 50,000<br />
poles a year to date. <strong>The</strong>y were, he said, going to test poles <strong>of</strong> native<br />
Thuya Plicata, Corsican Pine and Sitka Spruce for their suitability as<br />
transmission poles but he was very doubtful if Pinus Contorta would<br />
be suitable. In the first place it was very difficult to get a straight<br />
stem <strong>of</strong> P.e. <strong>of</strong> suitable dimensions and secondly the absorption <strong>of</strong><br />
cresote by P.e. was very high and could be as much as 25 lbs. per<br />
cubic foot which would make the prepared P.e. poles as dear as poles<br />
<strong>of</strong> other species.<br />
Mr. Bogue said that in many instances the sites <strong>of</strong> roadside belts<br />
and screens had been very badly chosen. <strong>The</strong>y had been put under<br />
telegraph and power lines and in due course it was found necessary to<br />
prune them. Even this operation is only too frequently badly carried<br />
out and the trees were mutilated and disfigured. This was certainly no<br />
encouragement to the farmer to plant for himself and a little more<br />
care in the planning and subsequent treatment <strong>of</strong> their screens and<br />
shelter belts by Local Authorities was indicated.<br />

ABSTRACT<br />
PROBLEMS IN TREE NUTRITION<br />
M. C Rayner and W. Neilson-Jones. Faber & Faber. 12/ 6.<br />
<strong>The</strong> pioneer work in afforesting poor soils has met with some<br />
inexplicable failures, instances occurring where, under normal cultural<br />
methods, even the least exacting <strong>of</strong> conifers either failed to grow or<br />
gave inconsistent results.<br />
To the late Dr. Rayner in particular must go much <strong>of</strong> the credit<br />
for the knowledge now available on tree nutrition and fertility in<br />
difficult moorland soils, and it is impossible to read this book without<br />
paying a tribute to her devotion to this hitherto unexplored aspect <strong>of</strong><br />
afforestation.<br />
In 1932 work on an elaborate research programme sponsored by<br />
the Forestry Commission was started by the authors on the dismal<br />
moorlands <strong>of</strong> Wareham Heath in the south <strong>of</strong> England, and the results<br />
<strong>of</strong> their investigations over many years are recorded in full in this book.<br />
Prior to the carrying out <strong>of</strong> this research it was generally agreed<br />
that mineral deficiencies were not the only limiting factors in nutrition<br />
but no information was available to substantiate or refute any <strong>of</strong> the<br />
various biological theories which had arisen. It was suggested that in<br />
the process <strong>of</strong> humus decomposition in these organic soils various<br />
substances directly inimical to growth were produced but these were<br />
neither identified nor even proven to exist.<br />
<strong>The</strong> authors have shown that toxic substances are present, that they<br />
are <strong>of</strong> biological origin and that they operate directly by inhibiting<br />
fungal growth. <strong>The</strong>se react on the trees, it is believed, by restricting<br />
root growth, impeding mycorrhizal formation and generally curtailing<br />
the supply <strong>of</strong> nutrients normally rendered available as a result <strong>of</strong> fungal<br />
activity. An indirect result is the accumulation <strong>of</strong> raw humus with a<br />
high CN. ratio.<br />
On Wareham Heath Dr. Rayner applied organic compounds that<br />
brought about remarkable improvements in plant growth. <strong>The</strong> improvement<br />
was believed to be complex in origin, and highly specialised and<br />
intensive research by a team <strong>of</strong> ecologists, botanists and plant physiologists<br />
was undertaken towards obtaining evidence on which the above<br />
conclusions are based. Dr. Rayner believed that the quality <strong>of</strong> the<br />
organic substrate in the natural soil was <strong>of</strong> primary importance and<br />
thus the necessity <strong>of</strong> bringing about a change in the biological activity<br />
was apparent to her. It was found that composts removed toxic<br />
substances permanently as no other means could, and brought an end<br />
to their further production. <strong>The</strong>y operate by modifying the activities<br />
<strong>of</strong> the micro-flora already present, as proved by the enormously<br />
accelerated rate <strong>of</strong> cellulose breakdown etc. Evidence is provided that<br />
the basis for these changes lies in the organic constituents <strong>of</strong> the<br />
compost rather than in the inorganic (mineral) nutrients it contains.
30<br />
<strong>The</strong> effect <strong>of</strong> composts on growth <strong>of</strong> various species <strong>of</strong> pines is<br />
partly attributed to the establishment <strong>of</strong> mycorrhizal associations with<br />
possibly an indirect action through stimulation <strong>of</strong> soil fungi in general.<br />
Beneficial root fungi are normally present in the soil though <strong>of</strong>ten<br />
in a dormant state from which they can be released by composts which<br />
stimulate short root growth and production <strong>of</strong> mycorrhizae. Initial<br />
growth <strong>of</strong> short roots may be due to the production <strong>of</strong> growth promoting<br />
substances as a result <strong>of</strong> the vigorous fungal metabolism.<br />
In the course <strong>of</strong> the investigations many species and forms <strong>of</strong> root<br />
fungi were identified, some for the first time in these islands. <strong>The</strong><br />
organisms responsible for the production <strong>of</strong> toxic substances are,<br />
however, still unidentified but a technique <strong>of</strong> biological analysis was<br />
developed that makes it possible to estimate the relative degree <strong>of</strong><br />
toxicity in any given soil sample. <strong>The</strong> use <strong>of</strong> this technique has shown<br />
that toxicity occurs in several soils other than Wareham and it is<br />
recommended in solving practical problems <strong>of</strong> afforestation.<br />
In conclusion the authors discuss the bearing <strong>of</strong> these results on<br />
the practical control <strong>of</strong> fertility and plant nutrients. <strong>The</strong> importance<br />
<strong>of</strong> differential biological activity in a natural soil is emphasised.<br />
Qualitative difference in the resultant products may be determined by<br />
the action <strong>of</strong> varying local conditions on these activities at any stage<br />
and fertility depends on the maintenance <strong>of</strong> correct biological balance.<br />
Addition <strong>of</strong> mineral nutrients, aeration <strong>of</strong> the soil by mechanical treatment<br />
etc., while effective to a degree, cannot <strong>of</strong> themselves guarantee<br />
permanent amelioration. Biological activity must be guided along<br />
certain lines, e.g. by control <strong>of</strong> the litter in the forest, selective planting<br />
etc. Where degenerative changes have progressed beyond a certain<br />
point it may be easier and quicker to initiate a change by application<br />
<strong>of</strong> suitable organic materials.<br />
Finally in this very complex problem the conclusion is drawn that<br />
there is great need for further research.<br />

REVIEWS<br />
Northern Coniferous Forest Soils.<br />
By Ol<strong>of</strong> Tamm. Translated from the Swedish by Mark L. Anderson.<br />
Published by <strong>The</strong> Scrivener Press, Oxford. 17/6.<br />
In his preface to this English translation <strong>of</strong> his treatise on the<br />
Forest Soils <strong>of</strong> north Sweden, the author claims that the work has not<br />
been planned as a comprehensive scientific text-book. Be that as it<br />
may, the forester who is concerned with coniferous plantation will find<br />
that virtually all the essential general aspects <strong>of</strong> his soil problems are<br />
here dealt with in an eminently readable and authoritative way.<br />
Although primarily concerned with north Swedish conditions, the book<br />
is sufficiently broad in its scope to be <strong>of</strong> immediate interest to workers<br />
in other areas.<br />
In soil science text-books, many features <strong>of</strong> soils which are <strong>of</strong><br />
fundamental interest in forestry are apt to be treated somewhat casually,<br />
as being but incidental to soils in general. In Pr<strong>of</strong>essor Tamm's book<br />
the forestry interest is at all times predominant. I would cite his<br />
chapter on the mull and mor forms <strong>of</strong> humus as illustrative <strong>of</strong> the<br />
particular value to the forester <strong>of</strong> his specialised approach. In this<br />
he gives an insight to the influence <strong>of</strong> decomposition processes in the<br />
humus <strong>of</strong> the forest litter on the success or failure <strong>of</strong> natural<br />
regeneration.<br />
<strong>The</strong>re is sufficient general scientific treatment <strong>of</strong> north European<br />
soils in this book to serve the practical forester in northern latitudes as<br />
a text. Those who work in a climate which does not possess the severity<br />
<strong>of</strong> the north Swedish winter can reasonably make allowances in interpreting<br />
some <strong>of</strong> its conclusions in the light <strong>of</strong> their own working<br />
conditions.<br />
I would mention in conclusion that Pr<strong>of</strong>essor Tamm's reputation as<br />
a soil scientist extends considerably beyond the shores <strong>of</strong> Sweden. One<br />
need have no hesitation in accepting his views on Swedish forest soils<br />
as being based on long experience and sound judgment. <strong>The</strong> translator<br />
has produced a text which reads as fluently as an original composition.<br />
P.H.G.<br />
<strong>The</strong> Selection <strong>of</strong> Tree Species.<br />
Mark L. Anderson. Oliver and Boyd. 14() pp. 12/().<br />
<strong>The</strong> aim <strong>of</strong> this book can best be expressed in the words <strong>of</strong> the<br />
Author's Introduction: "to strive to provide what still seems to be<br />
lacking-some relatively objective means <strong>of</strong> distinguishing and classifying<br />
plantable site types which will serve, not only as an aid in the<br />
choice <strong>of</strong> tree species, but as a basis upon which a sound sylvicultural<br />
practice can be built." That final phrase is typical <strong>of</strong> the author's<br />
outlook. He is not satisfied merely to provide us with a method <strong>of</strong><br />
choosing a species which will produce a crop on any particular planting<br />
site but he aspires to relate his choice so closely to all the site factors<br />
that something approaching the natural ecological unit will result.<br />
Such a unit under proper management will have considerable powers
32<br />
<strong>of</strong> resistance to disease and may well be capable <strong>of</strong> natural regeneration,<br />
even though the species used be exotic.<br />
As in his previous booklet (published in 1932) Dr. Anderson<br />
relies on the ecological method <strong>of</strong> selection. He has summarised his<br />
experience in two tables based on six fertility and four moisture<br />
classes; the first table distinguishes twenty plant communities for which<br />
the second table lists suitable species in 'ready-reckoner' fashion. In<br />
addition he has included a useful section on other aids to locality<br />
assessment-data to be gleaned from existing stands or cleared woodlands,<br />
from geological and topographical maps, from general and local<br />
information etc. <strong>The</strong>re is also a section which summarises for all the<br />
species in common use in afforestation valuable information under<br />
such heads as Range and Importance, Ecology, Uses <strong>of</strong> Timber, Scope<br />
for Use, and Technique. <strong>The</strong>re are 21 excellent photographs to<br />
illustrate the text.<br />
<strong>Irish</strong> foresters will note that the selections recomended are those<br />
which have been put into practice with good results in our own State<br />
forests over the past 20 years. Thanks to the implementation <strong>of</strong><br />
Dr. Anderson's ideas, as now expressed in this book, it can be fairly<br />
claimed that <strong>Irish</strong> selections show a very sensitive response to site<br />
factors. In other respects too, particularly in the use <strong>of</strong> Pinus contorta,<br />
practice here has taken a distinctive and pioneer course which is likely<br />
to be followed elsewhere. A careful study <strong>of</strong> the author's remarks on<br />
tree species is strongly recommended and we would be glad to see<br />
him enlarge on these observations at some future date.<br />
We would have wished that the author had enlarged on the<br />
descriptions <strong>of</strong> soil types corresponding to his typical plant communities<br />
using the modern descriptions <strong>of</strong> soils based on differentiation into<br />
horizons. It is felt that a systematic description <strong>of</strong> soils using macroscopic<br />
characteristics only and which could be applied without undue<br />
difficulty in the field would add considerably to the value <strong>of</strong> this work<br />
and would help the user to avoid error and to place the site in its<br />
correct class with greater certainty.<br />
<strong>The</strong> author anticipates that some subdivision <strong>of</strong> his general<br />
vegetational types may be necessary within specific regions and this<br />
would appear to be the case at the lower end <strong>of</strong> the fertility scale for<br />
Ireland. Unfortunately our western peat types have been insufficiently<br />
studied from the aspect <strong>of</strong> pure ecology as well as from the aspects <strong>of</strong><br />
plantability and selection, and further research and experimental plantings<br />
are indicated and may enable us to elaborate on the author's<br />
more general classification. Further research is also indicated for our<br />
limestone esker ridges and shallow soils over limestone pavement and<br />
also for our Calluna-Molinia community which appears to be a<br />
degradation <strong>of</strong> the Calluna heath type as described by him and which<br />

One might have expected in a work <strong>of</strong> this nature some reference<br />
to the modern technique <strong>of</strong> mechanical cultivation and manurial applica-

tions and how far they can be expected to alter permanently the<br />
essential characteristics <strong>of</strong> the site. Nevertheless this work represents<br />
the first comprehensive appro_ch in these islands to a very intricate<br />
problem and is likely to reman for many years an invaluable aid in<br />
selection. No forester should neglect its careful and detailed study.<br />

<strong>The</strong> establishment and development <strong>of</strong> the Forest Service was one<br />
<strong>of</strong> the great achievements <strong>of</strong> British Rule in India. When the final<br />
break came that sub-continent had a sound forest policy enshrined in<br />
legislation and implemented by a personnel <strong>of</strong> the highest standing.<br />
Partition and the formation <strong>of</strong> the new state <strong>of</strong> Pakistan gave rise to<br />
many problems not the least <strong>of</strong> which was the organisation <strong>of</strong> a forest<br />
service under the most difficult circumstances. <strong>The</strong> far-famed Training<br />
and Research Institute at Dehra Dun went to India and Pakistan was<br />
left with no training centre, no place for research no decent library<br />
and, perhaps the most severe hardship <strong>of</strong> all, a service sadly depleted<br />
in senior staff and specialists. In view <strong>of</strong> this combination <strong>of</strong> adverse<br />
conditions, we must congratulate Pakistan on the establishment so soon<br />
<strong>of</strong> a technical journal and we. must also record our pleasure at the<br />
progress in organisation recorded therein.<br />
<strong>The</strong> first number runs to 94 pages and· contains ten original articles<br />
besides abstracts, reviews and letters-a very creditable achievement.<br />
<strong>The</strong> article <strong>of</strong> most general interest is contributed by the Editor,<br />
S. A. A. Anvery and treats <strong>of</strong> Forest and Forestry Problems <strong>of</strong><br />
Pakistan. <strong>The</strong> two wings <strong>of</strong> Pakistan are 1,500 miles apart and there<br />
is a corresponding divergence in climate, vegetation and forest<br />
problems, conditions varying from the arid, practically rainless expanses<br />
<strong>of</strong> Baluchistan to the extremely wet areas <strong>of</strong> East Pakistan with a<br />
rainfall <strong>of</strong> over 200 inches. <strong>The</strong> nominal forest area <strong>of</strong> over 83 million<br />
acres represents 5.33% <strong>of</strong> the land surface but many areas designated<br />
as forest are in fact treeless. This small proportion <strong>of</strong> forest is largely<br />
due to incidence <strong>of</strong> population. Due to the almost complete lack <strong>of</strong><br />
alternative fuels, firewood is <strong>of</strong> even greater importance than commercial<br />
timber and fetches a price in excess <strong>of</strong> that <strong>of</strong> wheat in<br />
pre-1942 years. Partition has left the country without a paper industry<br />
and it is planned to start two big mills in either wing. To make for<br />
closer utilisation <strong>of</strong> all the products <strong>of</strong> the forests it is proposed to<br />
establish an integrated industry or 'combinate' to produce timber, paper,<br />
matches, plywood, fibre board, gums, resins, oils, chemicals, etc.<br />

SEVENTH ANNUAL EXCURSION<br />
Report by M. SWAN, B.AGR.SC.<br />
THE <strong>Society</strong>'s 7th Annual Excursion was held on the 23rd, 24th and<br />
25th May, 1950, to the Wick;low district and we had the pleasure<br />
<strong>of</strong> having as guests some <strong>of</strong> our Welsh hosts <strong>of</strong> the previous year.<br />
Those who made the trip from Wales were Mr. F. C. Best, conservator<br />
for North Wales, Mr. and Mrs. Harrison, Messrs. A. J. Davies, R.<br />
W . Waters, L. E. Hughes and J. Morris. This was probably the most<br />
successful excursion we have yet had, it certainly was the best attended,<br />
over 80 members and their friends attending each day, and many<br />
lively and interesting discussions arose. <strong>The</strong> party was based in Dublin<br />
and travelled each day by bus and car.<br />
First Day, 23rd May.<br />
<strong>The</strong> excursion opened with a visit to Ballintombay property <strong>of</strong><br />
Rathdrum forest. On assembly at this property Mr. Meldrum, on<br />
behalf <strong>of</strong> the Minister for Lands, welcomed the party, while Mr.<br />
McEvoy, our President, extended a particular welcome to our Welsh<br />
friends. <strong>The</strong> Convener, Mr. O. V. Mooney, then gave a brief history<br />
<strong>of</strong> Forestry in Ireland.<br />
Up to the beginning <strong>of</strong> the 18th century the history <strong>of</strong> <strong>Irish</strong> forests<br />
is almost entirely one <strong>of</strong> exploitation. About that time, however, the<br />
landlords began planting on their estates and their interest lasted for<br />
almost a century-and-a-half. With the decline <strong>of</strong> the large land-owner<br />
constructive forestry in general and planting in particular was<br />
abandoned, until at the beginning <strong>of</strong> the present century the State<br />
began to take an interest in forestry. Avondale was acquired as a<br />
forest school in 1903 and the first plantations were laid down in<br />
1905-6, but little serious progress was made until after the first<br />
World War. From 1923 to 1932 progress was steady but slow<br />
approximately 3,000 acres being planted each year. In 1932 a fresh<br />
impetus was given to forestry and by 1939 almost 73,000 acres <strong>of</strong><br />
State owned plantations had been laid down. <strong>The</strong> second World War<br />
then slowed down progress for a number <strong>of</strong> years but in 1950 with<br />
the planting <strong>of</strong> 8,000 acres the total <strong>of</strong> State owned plantations reached<br />
131,971 acres with a reserve <strong>of</strong> plantable land <strong>of</strong> just over 28,000<br />
acres. At the present time a policy has been initiated to step lip<br />
afforestation considerably and a 25 ,000 acre annual planting programme<br />
has been fixed as the first target which it is hoped to reach in 1952.<br />
An ultimate target <strong>of</strong> one million acres <strong>of</strong> plantation is being aimed<br />
at, which would represent a forest area <strong>of</strong> about 6'10 instead <strong>of</strong> our<br />
present figure <strong>of</strong> 1.5 % .<br />
<strong>The</strong> Convener then dealt in detail with the Wicklow district.<br />
Wicklow contains one <strong>of</strong> the biggest mountain massifs in Ireland and<br />
elevations OVer 2,000 feet are commoo. <strong>The</strong> central core and ridge <strong>of</strong>
35<br />
these mountains is granite while Lower Silurian rocks outcrop on either<br />
flank and on the east extend without interruption to the sea except<br />
for a small mass <strong>of</strong> Cambrian rock which occurs between Bray and<br />
Wicklow. <strong>The</strong> influence <strong>of</strong> glaciation is apparent in its deepened<br />
valleys and in its lakes. In the mountain mass the rainfall is about<br />
60 inches per annum and the humidity is high, with mists and fogs<br />
frequent. Towards the sea, however, the climate is comparatively dry<br />
and the rainfall <strong>of</strong> 35 inches per annum is below average for the<br />
country.<br />
Much <strong>of</strong> the high-lying ground in this district is very suitable for<br />
forestry, protection from the prevailing south-west wind- always a<br />
foremost consideration in forestry in this country- being afforded by<br />
the high-lying ridges <strong>of</strong> the massif. <strong>The</strong> total area <strong>of</strong> State owned<br />
plantations in this district is 24,600 acres with a reserve <strong>of</strong> plantable<br />
land <strong>of</strong> 5,600 acres. In addition an area <strong>of</strong> 210 acres is under nurseries<br />
which provide the greater part <strong>of</strong> the plant supply for the entire<br />
country.<br />
<strong>The</strong> party, led by the Convener, then proceeded to inspect<br />
Ballintombay property. <strong>The</strong> main interest was centred in the comparative<br />
growth <strong>of</strong> Pinus contorta, Pinus laricio and Pinus sylvestris in<br />
juxtaposition at approximately 1,100 feet elevation on an easterly but<br />
generally exposed slope the predominant vegetation <strong>of</strong> which was<br />
strong Calluna. <strong>The</strong> plantations were laid down in 1926 and the<br />
Pinus contort a now stood at 20 to 25 feet and was still vigorous. <strong>The</strong><br />
Corsican pine had only grown from 5 to 15 feet and was showing<br />
signs <strong>of</strong> deterioration, while the Scots pine had rarely bettered 4 feet<br />
and seemed to have gone into complete check. As the party continued<br />
its progress to 1,450 feet the Pinus contorta still continued vigorous<br />
and without showing any effects <strong>of</strong> the increased exposure which had<br />
then become severe. <strong>The</strong> almost complete failure <strong>of</strong> the Scots pine<br />
and to a lesser degree <strong>of</strong> the Corsican on the same ground and <strong>of</strong>ten<br />
in the lea <strong>of</strong> 15 ft. Pinus contorta stands was very striking. Mr.<br />
Best speaking in the discussion said he had never seen S.P. do so<br />
badly or P.e. do so well as here. P.e. was very little used in Wales<br />
but S.P. had been grown successfully at elevations up to 1,600 feet.<br />
Mr. Galvin suggested that the failure <strong>of</strong> the S.P. might have been due<br />
to the race <strong>of</strong> seed used and stressed the necessity for research in<br />
this direction.<br />
Also seen during the morning's inspection was a stand <strong>of</strong> Cupressus<br />
Macrocarpa 22 years old at an elevation <strong>of</strong> 800 feet on a slightly<br />
exposeci south-east slope. <strong>The</strong> soil was a light shaley loam and at the<br />
time <strong>of</strong> planting the site was a grass field in the early stages <strong>of</strong> reversion<br />
to Calluna. This stand the Convener said was probably the best <strong>of</strong><br />
e.M. in the country in point <strong>of</strong> form and quality, while measurements<br />
showed a mean annual increment <strong>of</strong> 112 cubic feet per acre. Mr. Forbes<br />
remarked that L.M. will not clean itself and has to be pruned, but<br />
that its timber was the most durable we could grow.
36<br />
In the afternoon the party visited Avondale Forester School and<br />
Forest. <strong>The</strong> Superintendent, Mr. T. O 'Carroll, speaking first in <strong>Irish</strong><br />
and Welsh and then in English welcomed the party to what may be<br />
termed the cradle <strong>of</strong> <strong>Irish</strong> State forestry and gave a brief outline <strong>of</strong> its<br />
history. From him we learned that Avondale House was built by<br />
one Samuel Hayes, who was an ardent lover <strong>of</strong> trees and the author<br />
<strong>of</strong> the first book published in Ireland on tree planting, a copy <strong>of</strong> which<br />
is kept in the School library. On his death the house and estate passed<br />
to Sir John Parnell, then Chancellor <strong>of</strong> the <strong>Irish</strong> Exchequer. Eventually<br />
it passed to Charles Stewart Parnell, leader <strong>of</strong> the <strong>Irish</strong> Parliamentary<br />
Party in Gladstone's Parliament. On his death the estate was sold to<br />
a Mr. Boylan <strong>of</strong> Dublin who in turn sold it in 1903 to the Dept. <strong>of</strong><br />
Agriculture and Technical Instruction for Ireland for forestry purposes.<br />
It then became the State Forester School and most present day<br />
foresters in Ireland have received their training here. Here also in<br />
1905-6 were laid down the first State-owned plantations, mainly in<br />
the form <strong>of</strong> one acre experimental plots <strong>of</strong> a wid:,: range <strong>of</strong> conifers<br />
and hardwoods, pure and in mixture. Much that has been learned<br />
at this centre has been applied in practice throughout the country.<br />
Very full descriptions <strong>of</strong> the plantations at Avondale will be found<br />
in Vol. III No. 2 and in Vol. VII Nos. 1 and 2 under the reports by<br />
Messrs. Maher and Deasy <strong>of</strong> previous visits to this centre. Only one<br />
or two <strong>of</strong> the outstanding plots therefore need mention here.<br />
One <strong>of</strong> the most important factors influencing the early development<br />
<strong>of</strong> the experimental plots was spring frosts. Records show that<br />
much damage was caused in 1907, 1909, 1911 and 1914. <strong>The</strong> greatest<br />
damage however was in 1911 when the frost occurred as late as 15th<br />
June and it took the damaged plants several years to recover from its<br />
effects. In the case <strong>of</strong> Abies pectinata many plants were killed outright<br />
and the effect on the remainder was permanent resulting in the almost<br />
complete failure <strong>of</strong> this species. <strong>The</strong> effects on the subsequent development<br />
<strong>of</strong> D .F. and Ash were also very pronounced while other Silver<br />
Firs, Spanish Chestnut, Oak and S.S. suffered to a less extent.<br />
Another important factor was the irregularity <strong>of</strong> thinning and<br />
attention generally. During and immediately after the First World<br />
War it was not found possible to devote the necessary attention to the<br />
plots and this neglect at a critical stage unfortunately upset the basic<br />
object <strong>of</strong> many <strong>of</strong> the experiments by allowing nurse species to<br />
dominate and suppress main crop species. Indeed when treatment did<br />
become possible it was <strong>of</strong>ten too late and the nurses had to be accepted<br />
as final crop trees. <strong>The</strong> history <strong>of</strong> the S.S.jJ.L. plot in this respect was<br />
<strong>of</strong> particular interest and showed the wonderful recuperative powers <strong>of</strong><br />
S.S. <strong>The</strong> original mixture <strong>of</strong> this plot was S.S. I J.L. 50/ 50 planted at<br />
four foot spacing. <strong>The</strong> spruce suffered severely from successive spring<br />
frosts and from Aphis attacks so that the J.L. outgrew and proceeded<br />
to suppress it. In 1927 it was concluded that the S.S. was past recovery<br />
many <strong>of</strong> them being mere bushes. However some tentative thinning
37<br />
and pruning <strong>of</strong> the J.L. was carried out and quite surprisingly the S.S.<br />
responded at once and in two or three years the apparently doomed<br />
S.S. were developing leading shoots <strong>of</strong> 2 to 3 feet. This spruce is now<br />
82 feet high with an average Q.G.B.H. <strong>of</strong> 10 inches and a mean annual<br />
increment <strong>of</strong> 109 cu. ft. U.B. per acre for the plot.<br />
<strong>The</strong> most outstanding plot seen was <strong>of</strong> course that <strong>of</strong> Abies grandis.<br />
This one acre plot was planted with Abies grandis/ Abies pectinata<br />
25/75 mixture. <strong>The</strong> latter species originally intended as a nurse was<br />
severely damaged by frost and eventually suppressed by the A.G.<br />
Records to date show a total production <strong>of</strong> 16,268 cu. ft. U.B. from<br />
this plot, which gives a mean annual increment <strong>of</strong> 361 cu. ft. U.B.<br />
per acre. Mr. Best remarked that in Wales they find Abies Nobilis<br />
superior to A.G. in the hills but that A.G. is the better in the lowlands.<br />
Nowhere, he said, had he seen anything at all comparable with<br />
the Avondale plot. Mr. Mooney pointed out that the yield, exceptional<br />
as it was, would probably have been much greater if proper attention<br />
could have been paid to thinning during the first 30 years or so. Mr.<br />
Clear, in a discussion on the present treatment <strong>of</strong> the stand, suggested<br />
further thinning as the trees were still vigorous and he hoped for<br />
natural regeneration.<br />
Second Day, 24th May.<br />
On the morning <strong>of</strong> the second day the party assembled at<br />
Glendalough for an inspection <strong>of</strong> part <strong>of</strong> that forest. Glendalough is<br />
famous both for its natural grandeur and for its monastery founded by<br />
St. Kevin in the 6th century. Despite plundering and pillaging by<br />
Danes and Anglo-Normans this monastery continued until 1398 when<br />
it was finally destroyed and deserted. It was a monastic settlement<br />
complete with churches, stone bee-hive cells, round tower, workshops,<br />
mill, dairy etc and was only at the beginning <strong>of</strong> its fame when St.<br />
Kevin died in 618 A.D. Practically the only ruins now remaining are<br />
those <strong>of</strong> the Churches which has caused Glendalough to be sometimes<br />
called the Valley <strong>of</strong> the Seven Churches. In 1876 however the<br />
foundations <strong>of</strong> an 8th Church were discovered and it is now generally<br />
believed that there was also a ninth Church the site <strong>of</strong> which has yet<br />
to be discovered.<br />
<strong>The</strong> area chosen for inspection was Lugduff property which lies<br />
on the south side <strong>of</strong> the lakes, the elevation being from 440 ft. at the<br />
lake side to 2,179 ft. at Mullacor one-and-a-half miles to the south.<br />
<strong>The</strong> underlying rocks throughout are <strong>of</strong> Upper Silurian origin micaschist<br />
being the usual derivative. Below the 1,100 ft. contour light shaley<br />
loams are met with and are very suitable for tree-growth. Above this<br />
contour however the rainfall averages over 60 ins., atmospheric conditions<br />
are very humid and peat is general. <strong>The</strong> influence <strong>of</strong> glacial<br />
action is very striking at Glendalough, the valley bottom was gouged<br />
out and both lakes owe their origin to the ice, the moraine being very<br />
evident across the valley near the round tower.
38<br />
<strong>The</strong> party began the ascent <strong>of</strong> Lugduff property on the new road<br />
constructed during the war years to give access to the upper areas<br />
for the extraction <strong>of</strong> thinnings, etc. Mr. Maher pointed out some <strong>of</strong> the<br />
difficulties met with in the construction <strong>of</strong> this road, the very steep<br />
gradients, the difficult bends and the embankments and bridges<br />
necessary, and how by careful planning they had been surmounted.<br />
He referred in detail to the question <strong>of</strong> capillary water and how best<br />
to deal with it.<br />
A stop was made in a D .F. plantation 28 years old and situated<br />
on a sheltered S/ E slope at 800 ft. elevation. <strong>The</strong> soil was a deep<br />
fertile shaley loam .with a high degree <strong>of</strong> moisture and was, before<br />
planting, a grass field near the houses <strong>of</strong> a mountain farm and in<br />
good heart. <strong>The</strong> crop now had an average height <strong>of</strong> 46 ft. and<br />
a Q.G.B.H . <strong>of</strong> 5! ins. while the yield was just 2,000 cu. ft. U.B. per<br />
acre. <strong>The</strong> general comment <strong>of</strong> the party expressed by Mr. Harrison<br />
was that the stand had been left too long before thinning. Mr. Best<br />
suggested fairly heavy and frequent thinning for D .F. as the canopy<br />
closes quickly and stressed the necessity for starting early. Mr. Clear<br />
said that from stem analysis he had noticed that suppression in D .F.<br />
began at about 13 years for 6 ft. X 6 ft. planting and consequently<br />
early thinning was essential. He suggested a thinning cycle <strong>of</strong> 3 years.<br />
He also referred to the very fine natural regeneration <strong>of</strong> D.F. at Lough<br />
Gill forest seen during our excursion to the Sligo district.<br />
<strong>The</strong> party then passed through a stand <strong>of</strong> E.L. / J.L. planted in 1922<br />
and showing very clearly the lack <strong>of</strong> success that is experienced with<br />
E.L. at high elevations in this region. <strong>The</strong> ground was <strong>of</strong> very good<br />
quality with grass and bramble predominant in the vegetation and<br />
while the J.L. had done well the E.L., 28 years old was very poor indeed.<br />
In contrast to what we had seen on the first day at Ballintombay<br />
we found here at Lugduff a promising stand <strong>of</strong> S.P. at 1,100 ft.<br />
elevation. This crop was on a steep southern slope and in an exposed<br />
situation, soil and drainage conditions however were excellent.<br />
From a natural grandstand, overlooking the lakes we had a wonderful<br />
view <strong>of</strong> this historic beauty spot and Mr. McEvoy described the<br />
vegetation <strong>of</strong> the district in general and gave an account <strong>of</strong> the old<br />
system <strong>of</strong> farming, "boleying", practised in these regions by which<br />
the farmer drove his flocks to the high hills and set up house there<br />
during the summer returning to the lowland enclosures for the winter.<br />
On returning to the natural oak-wood on the lake shore Mr.<br />
McEvoy gave a short lecture on Our Natural Sessile Oak-woods, after<br />
which the party adjourned for a picnic lunch on the lake-shore.<br />
After lunch the party travelled to Glenmalure forest which with an<br />
area <strong>of</strong> 6,478 acres has the distinction <strong>of</strong> being the largest forest centre<br />
in the country. It also has the distinction <strong>of</strong> having our highest-lying<br />
plantation as in it we find a stand <strong>of</strong> fairly good S.S. at approximately<br />
1,750 ft. elevation. Road construction is at present the biggest operation<br />
at this centre and thinning (which is the most important work)
39<br />
has been dependent to a great extent on its progress. As the labour<br />
supply is not sufficient to cope with both operations together the<br />
question <strong>of</strong> whether in the interests <strong>of</strong> economics thinning and road<br />
construction should proceed together or in the interests <strong>of</strong> sylviculture<br />
thinning should take precedence was debated with the honours about<br />
even.<br />
Glenmalure is a narrow steep-sided valley <strong>of</strong> glacial origin. Elevation<br />
ranges from 400 ft. to over 3,000 ft. On the south and west the<br />
rock formation is mainly granite while mica-schists with quartzite<br />
intrusions occupy most <strong>of</strong> the north and east.<br />
<strong>The</strong> party first inspected the new road being constructed at Ballyboy<br />
property and Mr. Maher pointed out how the lesson learned at<br />
Glendalough had been applied here. Of particular interest was a<br />
recently constructed river ford. <strong>The</strong> stones, Mr. -Maher told us, should<br />
for the best and most lasting results be placed vertically and not<br />
horizontally as might at first be expected. He stressed the necessity<br />
for beginning construction in the centre <strong>of</strong> the stream and working<br />
towards either side to ensure that every stone is locked in position.<br />
<strong>The</strong> species mainly used in Glenmalure were S.S. D.F. and larches<br />
with S.P. and P.e. <strong>The</strong> S.S. has been greatly retarded by continued<br />
severe frosting during its early life but it has now come through and<br />
a first quality crop has in many cases been established. A short stop<br />
was made in an S.S. stand in Compartment 35 which carried over<br />
4,000 cu. ft. U.B. per acre at 26 years <strong>of</strong> age.<br />
Next came a stand <strong>of</strong> D.F./ J.L. originally planted in SO/ SO<br />
mixture at 6 ft. X 6 ft. Unfortunately the J.L. had been allowed to<br />
dominate and suppress the D.F. and will now have to be accepted as<br />
the main crop species. Mr. Clear doubted the advisability <strong>of</strong> a<br />
D.F.jJ.L. mixture. He considered it a particularly doubtful mixture<br />
in areas like Glenmalure where the necessary labour was not available<br />
for cleaning and thinning at the critical time and unlike S.S. D.F.<br />
will not recover from suppression. That D .F. when planted pure was<br />
capable <strong>of</strong> quite good yields in this area however was seen during the<br />
afternoon ramble.<br />
Continuing the ascent the party again noticed the failure <strong>of</strong> S.P.<br />
on the 1,000 ft. contour. <strong>The</strong> area was originally planted with E.L./S.P.<br />
SO/ SO mixture in 1923 but was cleared in 1949 only a few <strong>of</strong> the<br />
best S.P. being retained and the area replanted with S.S. <strong>The</strong> situation<br />
is exposed with south-west aspect but soil conditions are good and<br />
moist. <strong>The</strong> S.S. is now doing quite well and the main problem now is<br />
deer and weevil damage.<br />
Before beginning the descent to the cars the party scrambled out<br />
on to the noted Michael Dwyer Rock overlooking the historic glen<br />
and Mr. Maher gave us an account <strong>of</strong> Glenmalure, its history, and its<br />
association with the O'Byrnes and the O'Tooles, and in more recent<br />
times <strong>of</strong> its part in the Rising <strong>of</strong> 1798 and <strong>of</strong> Michael Dwyer.
40<br />
In the descent the party passed through some stands <strong>of</strong> D.F.<br />
planted pure at 6 ft. X 6 ft. in 1926. <strong>The</strong>y were on a steep south-east<br />
slope in an exposed situation but with a deep well-drained soil and<br />
were quite promising. <strong>The</strong> average volume per acre under bark was<br />
1,350 cu. ft. while the average tree had a total height <strong>of</strong> 37 ft. with<br />
a timber height <strong>of</strong> 24 ft. and a mid quarter girth <strong>of</strong> 3-! inches.<br />
Before dispersal the party inspected a timber-chute for extraction<br />
<strong>of</strong> material from the difficult and inaccessible upper slopes <strong>of</strong> the glen.<br />
On Wednesday night the <strong>Society</strong> entertained our Welsh guests and<br />
all those associated with the excursion to dinner in the Dept. <strong>of</strong> Lands<br />
Luncheon Club, Upper Merrion Street. <strong>The</strong> Minister for Lands was<br />
unfortunately unable to attend but was represented by Mr. Nally,<br />
Secretary <strong>of</strong> the Dept.<br />
Third Day, Tuesday, 25th May.<br />
<strong>The</strong> third and last day <strong>of</strong> the excursion was spent at Aughrim<br />
Forest. This forest comprises some 2,835 acres and the early plantings<br />
date from 1922. It is made up <strong>of</strong> a number <strong>of</strong> scattered properties<br />
around Aughrim village together with some larger and more compact<br />
mountain areas which stretch for some seven miles along the eastern<br />
side <strong>of</strong> the Ow River valley. Ballinglen Forest, some 2,900 acres in<br />
extent, lies on the western side <strong>of</strong> the Ow valley and was once part <strong>of</strong><br />
Aughrim Forest.<br />
As at Glenmalure and Glendalough glacial action has greatly<br />
influenced the topography <strong>of</strong> the Ow valley. Silurian rock again is<br />
met with mostly but outcrops <strong>of</strong> granite and Cambrian rock are not<br />
infrequent. A wide variety <strong>of</strong> site-qualities is met with in this forest<br />
ranging from rich sheltered old woodland sites at 150 ft. elevation to<br />
difficult calluna-molinia peat types at 1,500 ft.<br />
An annual planting programme <strong>of</strong> over 100 acres has been maintained<br />
at this centre over recent years but at present the most important<br />
operation is thinning. Road construction has as far as possible kept<br />
pace with thinning and a small portable mill has been operated for<br />
the conversion <strong>of</strong> the thinnings into boxwood, pitwood, fencing<br />
materials, etc.<br />
A nursery <strong>of</strong> some 19 acres is maintained at this forest and was<br />
among the first areas visited for the day. Mr. Ryan said that this nursery<br />
has been in continuous use for the past 30 years and that it had now<br />
been decided to rest it. Consequently it now had only a small area<br />
under seed beds, the remainder being under green crop. <strong>The</strong> soil was<br />
light and friable and easily worked and produced good S.S. transplants.<br />
Until recently, he said, most <strong>of</strong> our nursery areas had been concentrated<br />
in Wicklow but now we were going further afield and nursery ground<br />
was being acquired in all areas where there existed large tracts <strong>of</strong><br />
potential forest lands, as shown by the recently completed Survey <strong>of</strong><br />
Plantable Land. He also pointed out that as a direct result <strong>of</strong> our visit
4l<br />
to Wales the previous year a heath-land nursery was now being<br />
established_<br />
<strong>The</strong> first plantation visited was a mixed D.F-/J.L. 50/ 50 mixture<br />
planted in 1923. <strong>The</strong> site was an old oak woodland with a deep welldrained<br />
soil <strong>of</strong> Silurian origin and the area was sheltered. Unfortunately<br />
the first thinning was not until 1945 with the result that the J.L. had<br />
suppressed the D.F. and was now the main crop. Mr. Harrison agreed<br />
with the thinning as it had been carried out, while Mr. Morehead<br />
suggested that a much heavier thinning over a small area might be<br />
carried out as an experiment.<br />
Among other plots seen was one <strong>of</strong> Abies Grandis/ J.L. planted in<br />
1923 at 6 ft. X 6 ft. This was also on an old oak woodland area with<br />
a deep well-drained soil <strong>of</strong> Silurian origin. <strong>The</strong> elevation was about<br />
400 ft. and the aspect southern but the area was not exposed. TI-:e<br />
stand was not thinned until 1947 and at the time <strong>of</strong> our visit was<br />
marked for a further thinning. <strong>The</strong> Abies Grandis was deliberately<br />
favoured in thinning and now completely predominates and is very<br />
vigorous with a current shoot-growth <strong>of</strong> over two feet. <strong>The</strong> average<br />
tree had a total height <strong>of</strong> 65 feet with a timber height to 3 inches <strong>of</strong><br />
47 ft. while the Q.G. at B.H. was 7 inches. <strong>The</strong> stems were well<br />
formed with little taper and the Q.G. at half timber height was 6<br />
inches. <strong>The</strong> larch on the other hand had a timber height <strong>of</strong> only 34<br />
ft. and a B.H.Q.G. <strong>of</strong> 5! inches. <strong>The</strong> A.G. had a volume <strong>of</strong> 4,440<br />
cu. ft. per acre while the J.L. had only 200 cu. ft. per acre giving a<br />
total <strong>of</strong> 4,640 cu. ft. per acre for the plot.<br />
<strong>The</strong> party then visited a series <strong>of</strong> D.F. plots at Roddenagh and<br />
Killaduff. A comprehensive survey and assessment <strong>of</strong> these areas had<br />
been carried out by Mr. Clear and detailed figures were available to<br />
the party for the stands visited. An account <strong>of</strong> this survey in relation<br />
to D.F. and the lessons to be learned from it has been contributed by<br />
the assessor, Mr. Clear, and appears in this issue.<br />
At the conclusion <strong>of</strong> the excursion Mr. McEvoy thanked the<br />
Minister for Lands and his staff for the facilities accorded the <strong>Society</strong><br />
and for the careful and painstaking arrangements they had made.<br />

Excursion to Killakee Forest<br />
Report by D. M. O·SULLIVAN.<br />
AN excursion to Killakee Forest was held on the afternoon <strong>of</strong> July<br />
8th, 1950. This Forest is on the Dublin foothills about 3 miles<br />
from Rathfarnham and the soil is <strong>of</strong> granite origin. <strong>The</strong> weather<br />
conditions were ideal and a large party attended.<br />
At the outset Mr. Swan (Convener) welcomed the party on behalf<br />
<strong>of</strong> the Minister for Lands. He then gave details <strong>of</strong> the progress <strong>of</strong><br />
the forest to date. <strong>The</strong> party was then conducted to what might be<br />
termed the Pinetum <strong>of</strong> the forest. Here in picturesque surroundings<br />
were to be found tree species from four continents and an interesting<br />
discourse on the characteristics <strong>of</strong> each <strong>of</strong> the species in view was<br />
given by the Convenor.<br />
<strong>The</strong> party then proceeded to a pure ash plantation on an area<br />
which was surrounded by a mature hardwood belt. <strong>The</strong> planting was<br />
carried out in 1938 and the spacing was 4' X 4'. <strong>The</strong> vegetation on<br />
half <strong>of</strong> the area was meadow grasses, while nettles predominated on<br />
the other half. <strong>The</strong> trees on the latter area got away rapidly while<br />
those on the ground carrying the mat <strong>of</strong> grass were very slow in the<br />
early stages and at present (1950) there would be the equivalent <strong>of</strong><br />
4 years difference as regards rate <strong>of</strong> growth. In 1944 half <strong>of</strong> the<br />
hardwood belt on the side nearest the ash was removed as the ash<br />
was inclined to lean away from the belt due to excess shade. <strong>The</strong><br />
area where nettles predominated at time <strong>of</strong> planting got a weeding<br />
in the summer <strong>of</strong> 1946. In this operation the rough and badly-shaped<br />
stems, mostly wolves were removed . Subsequent thinnings were carried<br />
out in 1947 and 1948 when the number <strong>of</strong> stems was reduced to<br />
eight hundred per acre. At this stage Tsuga Heterophylla and Thuya<br />
Plicata were introduced as an under storey. <strong>The</strong> average height <strong>of</strong> this<br />
area is 23 ft. and the average Q.G.B.H. is 3i ins. <strong>The</strong> area carrying<br />
grasses at time <strong>of</strong> planting had not got any treatment other than<br />
pruning <strong>of</strong> double leaders as it had not yet reached the weeding stage.<br />
<strong>The</strong> party agreed that this was a fine stand <strong>of</strong> ash both as regards rate<br />
<strong>of</strong> growth and immunity from disease. Mr. Clear was <strong>of</strong> the opinion<br />
that it may have been the leaf-fall from the surrounding belt that was<br />
responsible for so marked a difference in the rate <strong>of</strong> growth and that<br />
the removal <strong>of</strong> the hardwood belt would be detrimental rather than<br />
beneficial to the plantation. He did not favour the introduction <strong>of</strong><br />
the shade bearers which he feared would create undue root competition<br />
which would retard the growth <strong>of</strong> the ash. He was <strong>of</strong> the opinion<br />
that the thinning might have been more severe.<br />
<strong>The</strong> next area visited was planted with oak, beech and horse<br />
chestnut in equal proportions. Very little <strong>of</strong> the horse chestnut remains<br />
possibly due to damage by hares which despite constant snaring are<br />
still numerous on the area. During the eight weeks blizzard <strong>of</strong> 1947<br />
the area became infested with hares and the damage caused to the
43<br />
horse chestnut was notable In companson to that caused to the beech<br />
and the oak. <strong>The</strong> bark <strong>of</strong> the horse chestnut was completely stripped<br />
for nearly 4 feet above snow level, while the damage to the beech<br />
was slight and to the oak, negligible.<br />
Japanese Larch except for one small area was included as a nurse<br />
through the hardwoods at 20' X 20'. <strong>The</strong> ground vegetation at time<br />
<strong>of</strong> planting varied from cocksfoot, meadow foxtail and meadow grasses<br />
on the better and more fertile ground to crested dogstail, sweet vernal<br />
grass, creeping cinquefoil, germander speedwell and birdsfoot trefoil<br />
on the drier and less fertile ground. As regards rate <strong>of</strong> growth the<br />
oak has done better on the better type ground while there is no<br />
appreciable difference in the case <strong>of</strong> the beech. On the ground where<br />
no Japanese Larch nurses were included the hardwoods are inclined to<br />
spread and be more bushy than elsewhere. <strong>The</strong> chief disadvantage <strong>of</strong><br />
Japanese Larch as a nurse was its rapid rate <strong>of</strong> growth and spreading<br />
habit which caused damage to the hardwoods and required pruning<br />
at an early stage. At ten years the height <strong>of</strong> the oak on the area<br />
averaged more than 4' which is the average for similar plantations<br />
grown by the British Forestry Commission. <strong>The</strong> removal <strong>of</strong> the<br />
Japanese Larch was being carried out.<br />
An interesting discussion took place concerning the past and future<br />
treatment <strong>of</strong> the plantation. Mr. Clear was <strong>of</strong> the opinion that ploughing<br />
<strong>of</strong> the ground at time <strong>of</strong> planting would have been more satisfactory<br />
than the system adopted. This method would have obviated<br />
grass clearing which was ·expensive. <strong>The</strong> absence <strong>of</strong> grass caused by<br />
ploughing would have given the plants a chance to get away in the<br />
early stages. Mr. Hayes suggested topping back the Japanese Larch<br />
to half height. This would have the effect <strong>of</strong> keeping the ground<br />
clean as well as continuing to encourage cleaner and straighter hardwood<br />
stems. Mr. Ryan was <strong>of</strong> the opinion that the removal <strong>of</strong> the<br />
nurse trees should have commenced earlier.<br />
<strong>The</strong> next stop was at an area planted pure with Spanish Chestnut<br />
at a spacing <strong>of</strong> 4' X 4'. Though the area was small the ground varied<br />
considerably and there is a notable difference in the crop both as<br />
regards rate <strong>of</strong> growth and number <strong>of</strong> good stems. <strong>The</strong>re was a<br />
gradual slope and the site quality varied from a moist loamy soil<br />
carrying cocks foot, meadow foxtail and timothy to a lighter and less<br />
fertile soil carrying sweet vernal grass, germander speedwell, crested<br />
dogstail, birdsfoot trefoil, knapweed, etc., on the higher ground. On<br />
the better type <strong>of</strong> ground there is a smaller proportion <strong>of</strong> bushy topped<br />
stems and the average height is 14'. <strong>The</strong>re is a gradual falling <strong>of</strong>f<br />
in height growth to the top <strong>of</strong> the slope where the height is only<br />
about 4' and where there are few clean straight stems. A number <strong>of</strong><br />
bushy topped trees were cut back in the spring <strong>of</strong> 1944 but<br />
unfortunately most <strong>of</strong> the resulting shoots were killed by the severe<br />
May frost <strong>of</strong> that year. A few escaped however and the advantage <strong>of</strong><br />
cutting back was very evident.
44<br />
On the last plot visited ash in the diamond-shaped beds <strong>of</strong> 13<br />
plants, 2' apart and 25' between the groups were planted in a matrix<br />
<strong>of</strong> Lawson Cypress pure at 4' X 4' the intention being to get one<br />
straight stem from each group <strong>of</strong> ash. <strong>The</strong> ash remained at a standstill<br />
in the early stages and looked as if it were going to be a failure. When<br />
the Lawson Cypress killed out the ground cover <strong>of</strong> grass the ash made<br />
rapid growth and now exceeds the Lawson Cypress in current height<br />
growth. <strong>The</strong> height <strong>of</strong> the ash at present is about 20'. In each group<br />
most <strong>of</strong> the ash llave been removed and a few good stems left from<br />
which the one finally selected will be chosen. <strong>The</strong> Lawson Cypress<br />
crop carries a number <strong>of</strong> rough and forked trees. Both Mr. Ryan and<br />
Mr. McEvoy were <strong>of</strong> the opinion that the race <strong>of</strong> the seed was<br />
responsible. Mr. Clear while admitting that the stand did not look<br />
as one would expect, considered that with careful sylvicultural treatment<br />
it should develop into a successful crop.<br />
Excursion to Dundrum Sawmill and<br />
Forest<br />
Report by F. G. MORIARTY.<br />
THE <strong>Society</strong> concluded its year's outings with a very successful<br />
excursion to Dundrum Forest and Sawmills on 22nd October, 1950,<br />
the attendance exceeding 100. Mr. Haas, District Officer, welcomed the<br />
guests on behalf <strong>of</strong> the Minister for Lands and gave a resume <strong>of</strong> the<br />
improvements carried out at the Sawmills which were now completely<br />
modernized.<br />
Mr. Meldrum explained that, heret<strong>of</strong>ore, the absence <strong>of</strong> suitable<br />
machinery prevented us from utilizing our timber produce to ',he<br />
best advantage, but that now, the new electrically-driven machines and<br />
the drying kilns recently installed, would enable <strong>Irish</strong> timber to<br />
compete favourably with the best imported stock.<br />
Mr. Meldrum then conducted the party through the mill where they<br />
saw these new machines in operation. A large log <strong>of</strong> Oak was broken<br />
down on the electrically-driven Band Mill and then re-sawn into crossarm<br />
sizes and bored to E.S.B. specification. <strong>The</strong> members next<br />
inspected the two Drying Kilns. One <strong>of</strong> these was then charged with<br />
a bogey load <strong>of</strong> Scots Pine planks and the members were shown how<br />
the process <strong>of</strong> drying was initiated. Subsequent to this the machining<br />
<strong>of</strong> kiln-dried stock into tongued and grooved flooring boards on<br />
the "five cutter" was demonstrated. <strong>The</strong> finished product was greatly
45<br />
admired and all were convinced that Mr. Meldrum's statement, made<br />
at the outset "that <strong>Irish</strong> timber when subjected to proper treatment<br />
was second to none" was well and truly substantiated.<br />
At the request <strong>of</strong> some <strong>of</strong> the members a short run was made<br />
through the Forest. We visited Gurtussa Property, a block some<br />
ninety acres in extent, comprising in the main Sitka-Spruce with some<br />
Scots Pine and European Larch and planted during the years 1911 to<br />
1914. <strong>The</strong> members could observe here what judicious thinning and<br />
proper sylvicultural methods can achieve. Some truly magnificent Sitka<br />
Spruce stems were seen in the older 1911 plantations. Of an average<br />
breast height quarter girth O.B. <strong>of</strong> 13" and standing 68 feet in height<br />
they gave promise <strong>of</strong> a high timber yield on maturity.<br />
Mr. Haas outlined the history <strong>of</strong> the block and traced its life<br />
through the initial weeding and pruning operations and the various<br />
thinning stages, down the years, to the present date. Mr. Mooney<br />
started an interesting discussion with Mr. Clear on the Sylvicultural<br />
characteristics <strong>of</strong> the stand.<br />
We next traversed various Spruce woods more recently planted<br />
and saw how the work now being carried out was gradually bringing<br />
them into line with the one previously visited. An E. Larch stand in<br />
C. 30 aroused much interest. It was planted in 1919 and was bounded<br />
on the north north-west and south by Spruce blocks <strong>of</strong> the same age,<br />
and it was observed that considerable natural regeneration <strong>of</strong> Sitka<br />
Spruce had come in under the Larch. Wherever the Larch canopy was<br />
thin the young Spruce were doing very well. Mr. Grant, the forester,<br />
explained that a heavy thinning <strong>of</strong> Larch was intended and that then,<br />
by scarifying the ground, it was hoped to reseed the area with Sitka<br />
Spruce.<br />

NINTH ANNUAL GENERAL MEETING<br />
(Report by MISS R. McDONAGH and M. SWAN).<br />
THE Ninth Annual General Meeting <strong>of</strong> the <strong>Society</strong> was held in<br />
jury's Hotel at 7.30 p.m. on Friday, 16th March, 1950. <strong>The</strong><br />
President, Mr. T. McEvoy was in the chair and the large attendance<br />
filled the spacious room to capacity.<br />
On the suggestion <strong>of</strong> the President the minutes <strong>of</strong> the previous<br />
Annual General Meeting, which had already appeared in the Journal<br />
were taken as read and were signed.<br />
<strong>The</strong> President then called on the Secretary to read the report <strong>of</strong><br />
the Council for 1950.<br />
COUNCIL REPORT FOR 1950.<br />
<strong>The</strong> first meeting <strong>of</strong> the Council was held on the 4th February,<br />
1950. <strong>The</strong> new Council appointed sub-committees to deal with arrangements<br />
for excursions, the publication <strong>of</strong> the Journal, to look after<br />
finance and tree registration. Eleven members attended this meeting.<br />
<strong>The</strong> second meeting <strong>of</strong> the Council was held on the 3rd May. Nine<br />
members were present. Final arrangements for the Annual Excursion<br />
were completed and a dinner in honour <strong>of</strong> the Welsh visitors was<br />
arranged.<br />
A further meeting <strong>of</strong> the Council was held on May 24th. Six<br />
members attended. <strong>The</strong> main business was concerned with the arrangement<br />
<strong>of</strong> a programme <strong>of</strong> day excursions for the summer and autumn.<br />
Further meetings were held on 6th September and on the 29th<br />
November. Eight members attended each <strong>of</strong> these meetings.<br />
ME<strong>MB</strong>ERSHIP.<br />
During the year 18 Associate, 4 Grade I, and 27 Grade II members<br />
were enrolled. An analysis <strong>of</strong> the roll book shows that, with new<br />
enrolments and losses due to deaths, resignations and lapsed membership,<br />
there are now 118 Associate, 46 Grade I and 81 Grade II<br />
members.<br />
<strong>The</strong> growth <strong>of</strong> the <strong>Society</strong>, while not as rapid as the Committee<br />
would wish to have it, is satisfactory. With the growing interest in<br />
forestry in the country a good enrolment this year is anticipated and<br />
members are urged to do their utmost to encourage new members to<br />
join. It is felt that the best way <strong>of</strong> selling the forestry idea to the<br />
country is to bring the people into direct contact with the forest through<br />
the medium <strong>of</strong> excursions, attendance at excursions is the surest sign<br />
<strong>of</strong> interest in the <strong>Society</strong>'s activities.<br />
FINANCE.<br />
<strong>The</strong> abstract <strong>of</strong> accounts for the year 1950 could not be included<br />
with the notice <strong>of</strong> the Annual General Meeting. Owing to the Bank<br />
Strike, the Treasurer was unable to bring the accounts to audit in time.<br />
<strong>The</strong> statement is now to hand and has been circulated at this meeting.
47<br />
While the statement shows the balance to our credit to be in a<br />
very healthy state, it is apparent from a close analysis <strong>of</strong> the account<br />
that current expenditure barely covers current income. We had the<br />
cost <strong>of</strong> only one issue <strong>of</strong> the Journal to meet last year. We are again<br />
indebted to Mrs. A. H. Henry for a further donation <strong>of</strong> £25 to forward<br />
the work <strong>of</strong> the <strong>Society</strong>.<br />
JOURNAL.<br />
One issue <strong>of</strong> the Journal appeared during the period under review.<br />
Members and others have commented on the continued high standard<br />
<strong>of</strong> the Journal and the Council is satisfied that in spite <strong>of</strong> rising costs<br />
<strong>of</strong> printing and paper the Journal should continue to be published and<br />
that at least 2 issues should appear each year. <strong>The</strong> revenue from<br />
advertising and sales . is well maintained amounting this year to £30<br />
for the one issue. As a result <strong>of</strong> the work <strong>of</strong> our Business Editor many<br />
County Libraries are now stocking our Journal and this should have<br />
the effect <strong>of</strong> bringing our <strong>Society</strong> to the notice <strong>of</strong> a much wider public<br />
as well as improving our receipts.<br />
EXCURSION.<br />
<strong>The</strong> excursions held during the year were very well attended. <strong>The</strong><br />
Annual 3-Day Excursion was favoured with very good weather and<br />
there was a big turnout each day. Our Welsh guests were very pleased<br />
with their visit and indeed, their presence added enormously to the<br />
pleasure and benefit <strong>of</strong> the whole outing. <strong>The</strong> Convener, Mr. 0. V.<br />
Mooney, and the <strong>of</strong>ficers <strong>of</strong> the Forestry Division are deserving <strong>of</strong> the<br />
highest praise for the organisation and facilities put at our disposal on<br />
this and other occasions.<br />
<strong>The</strong> day excursions were all favoured with good weather in a year<br />
when fine days were few and far between. <strong>The</strong> areas visited were<br />
Killakee, Curracloe, Gort and Dundrum.<br />
AUGUSTINE HENRY MEMORIAL.<br />
On the occasion <strong>of</strong> the 8th Annual General Meeting the Council<br />
reported that with the approval <strong>of</strong> the Minister for Lands and the<br />
consent <strong>of</strong> Mrs. A. H . Henry, a Memorial Grove was to be planted at<br />
Avondale. <strong>The</strong> Council is pleased to report that the ground has been<br />
fenced and planted and that a memorial plaque is almost ready for<br />
erection. It is hoped to have the formal opening <strong>of</strong> the Memorial<br />
Grove in the early summer.<br />
<strong>The</strong> adoption <strong>of</strong> the Council's report and the Abstract <strong>of</strong> Accounts<br />
was proposed by Mr. Chisholm who congratulated the <strong>Society</strong> on<br />
its strong financial position and on its great activity and interest during<br />
the year. Mr. Ross seconded and the meeting unanimously agreed to<br />
the motion.
48<br />
THE President thanked the members for doing him the honour <strong>of</strong><br />
re-electing him for a second term <strong>of</strong> <strong>of</strong>fice and then proceeded to<br />
review the past year's developments in the world <strong>of</strong> forestry as<br />
follows :-<br />
PRESIDENT'S ADDRESS.<br />
"Looked at in a broad general way the present international forestry<br />
situation is still to a large extent a direct result <strong>of</strong> World War II.<br />
Apart from a few European countries like Germany, Switzerland<br />
and France where forest management has for centuries been the norm,<br />
the necessity for national forest policies came to be generally accepted<br />
only after World War 1. Substantially the forest policies <strong>of</strong> such<br />
countries as U.S.A., Canada, Britain, Ireland, Australia and New<br />
Zealand date from that period. World War II, with its mass destruction<br />
<strong>of</strong> the essentials <strong>of</strong> civilized existence and the enormous post war<br />
demand for timber for reconstruction, has re-emphasised the need for<br />
scientific management <strong>of</strong> existing forests and an extension <strong>of</strong> forest<br />
areas. Most countries have therefore been having a 'check-up' and have<br />
been formulating plans for large-scale afforestation. In so doing the<br />
experience gained in the inter-war period has been <strong>of</strong> immense value<br />
and it can fairly be said that the new plans are usually based on a<br />
more realistic appreciation <strong>of</strong> the problems involved.<br />
<strong>The</strong> first effects <strong>of</strong> these revisions <strong>of</strong> policies are now becoming<br />
evident but it is already clear that the unsettled world situation has<br />
taken its toll in so far as accomplishment falls short <strong>of</strong> target.<br />
In Britain for example according to the latest published figures,<br />
land acquisition progress has reached only 21% <strong>of</strong> the target figure.<br />
<strong>The</strong> planting reserve <strong>of</strong> 335,000 acres, itself considered inadequate,<br />
has been eaten into. Planting reached 76% <strong>of</strong> the target.<br />
In the older forest countries <strong>of</strong> Europe the problem is not so much<br />
one <strong>of</strong> afforestation as <strong>of</strong> making up for the war-time overcutting by<br />
reducing annual fellings to a figure equivalent to nett annual growth.<br />
It is with regret that we must record that this is not being accomplished.<br />
Even in Switzerland felling still exceeds normal growth by 22% .<br />
<strong>The</strong> War has had one beneficial effect in stimulating the application<br />
<strong>of</strong> mechanical methods to the diverse operations <strong>of</strong> the forest. Naturally<br />
the most spectacular results have been in logging and utilization but<br />
important advances have also been made in the nursery and in the<br />
use <strong>of</strong> crawler tractors in preparing ground for planting.<br />
You will recollect the damage done by forest fires in the Landes<br />
District <strong>of</strong> France last summer. <strong>The</strong> marketing <strong>of</strong> some 5 million cubic<br />
metres <strong>of</strong> fire-damaged timber has created havoc in the markets there.<br />
Some idea <strong>of</strong> the immensity <strong>of</strong> the problem may be gained if we<br />
remember that this quantity <strong>of</strong> timber would supply our total requirements<br />
for about six years.<br />
Turning to the utilization side, we find that recent trends have<br />
continued. <strong>The</strong> use <strong>of</strong> solid timber continues to be restricted both
49<br />
in constructional work and in furniture manufacture. On the other<br />
hand the consumption <strong>of</strong> fibre board, pulp, block board, plywood,<br />
veneers etc. is expanding rapidly. In my opinion this development<br />
should be welcomed by foresters as it increases the adaptability, versatility<br />
and competitive powers <strong>of</strong> wood in relation to other raw materials<br />
and in addition makes for economy and efficiency. In this connection<br />
it is <strong>of</strong> interest to note that the British Vampire jet fighter is constructed<br />
entirely <strong>of</strong> wood-Sitka Spruce and balsa woods.<br />
Timber prices, which tended to fall early in 1950, began to rise<br />
in the Autumn with the outbreak <strong>of</strong> war in Korea and the trend is<br />
still sharply upward. Paper pulp in particular is rising steeply and is<br />
likely to continue for long in short supply.<br />
We must now ask ourselves what developments <strong>of</strong> significance<br />
there were in <strong>Irish</strong> forestry during the year.<br />
<strong>The</strong> beginning <strong>of</strong> the year saw the field work <strong>of</strong> the Survey <strong>of</strong><br />
Plant able Land completed. <strong>The</strong> results showed that there are still<br />
some 1,200,000 acres <strong>of</strong> marginal and sub-marginal agricultural land<br />
and cleared woodland capable <strong>of</strong> growing timber crops. Adding to<br />
this figure an estimated 60,000 acres <strong>of</strong> stocked woodland in private<br />
ownership and some 170,000 acres <strong>of</strong> productive State forest lands<br />
we see that the total potential forest area is close on a million-and-ahalf<br />
acres. This survey has already proved <strong>of</strong> inestimable value in<br />
providing the solid basis <strong>of</strong> fact on which the F.A.O. mission could<br />
build policy proposals and it has enabled the Forestry Division to put<br />
the planning and control <strong>of</strong> land acquisition on a sounder basis.<br />
This brings us to the F.A.O. mission. Ireland was fortunate in<br />
securing the services <strong>of</strong> so distinguished a forester as D. Roy Cameron,<br />
Chief <strong>of</strong> the F.A.O. Forestry Group in Europe and past Director <strong>of</strong><br />
the Dominion Forest Service <strong>of</strong> Canada. His report which has just<br />
beeen made public is the first formal review <strong>of</strong> our forest policy since<br />
1908. It adopts the million acre target set by the Government in 1949.<br />
<strong>The</strong> programme is divided into two parts, commercial and social.<br />
<strong>The</strong> commercial policy <strong>of</strong> establishing half-a-million acres at an annual<br />
planting rate <strong>of</strong> 11,750 acres is designed to provide our minimum<br />
emergency requirements <strong>of</strong> 100,000 standards, equivalent to half the<br />
estimated maximum future consumption. This part <strong>of</strong> the programme<br />
would be concentrated in aggregations <strong>of</strong> not less than 3,000 acres on<br />
the more fertile forest soils.<br />
<strong>The</strong> other half-million acres <strong>of</strong> what Mr. Cameron terms 'social<br />
forestry' would be on the poorer soils which occur mainly in the west.<br />
This part <strong>of</strong> the programme is justified on the grounds <strong>of</strong> the indirect<br />
benefits to be derived in timber production, establishment <strong>of</strong> new<br />
industries, reclamation <strong>of</strong> idle lands, soil conservation, and relief <strong>of</strong><br />
congestion. To implement this policy involving a capital investment<br />
<strong>of</strong> the order <strong>of</strong> £100 million the creation <strong>of</strong> a new and separate Department<br />
<strong>of</strong> Forests is advocatec!,
50<br />
In actual forest operations the Forestry Division continued to<br />
progress with its enlarged programme. Planting was almost double the<br />
wartime figure and equalled the highest pre-war level while land<br />
acquisition showed a distinct upward trend. <strong>The</strong> nursery area is in<br />
process <strong>of</strong> being trebled from 300 to 900 acres. A particularly satisfactory<br />
feature is the steady growth <strong>of</strong> income from sales <strong>of</strong> forest<br />
produce which now exceed £100,000.<br />
On the industrial side an event <strong>of</strong> major significance was the<br />
establishment here <strong>of</strong> the Bowater Corporation <strong>of</strong> Newfoundland, the<br />
largest pulp manufacturers in the world. <strong>The</strong> creation <strong>of</strong> a pr<strong>of</strong>itable<br />
market for small thinnings will have a pr<strong>of</strong>ound influence on the<br />
economics <strong>of</strong> <strong>Irish</strong> forestry. <strong>The</strong> setting up <strong>of</strong> a modern saw mill<br />
and kiln-drying plant at Dundrum is another happy augury for the<br />
future <strong>of</strong> native timber.<br />
No review <strong>of</strong> the past year would be complete without a reference<br />
to the passing <strong>of</strong> the father <strong>of</strong> <strong>Irish</strong> forestry, A. C. Forbes. For 26<br />
crucial years he was responsible for the initiation and development <strong>of</strong><br />
State afforestation and his death marks the end <strong>of</strong> an era.<br />
EXCURSION.<br />
<strong>The</strong> President announced that arrangements were now well<br />
advanced for the forthcoming annual excursion which this year would<br />
be to Scotland. He said that Mr. Clear had very generously donated<br />
£15 to cover the expenses <strong>of</strong> one forester on the excursion. <strong>The</strong> <strong>Society</strong><br />
was also providing an equal sum to defray the expenses <strong>of</strong> a second<br />
forester. A sub-committee had been appointed to see that the two<br />
lucky foresters would be chosen "by all the laws <strong>of</strong> chance."<br />
ELECTION OF MR. M. O'BEIRNE<br />
TO HONORARY ME<strong>MB</strong>ERSHIP.<br />
Mr. Meldrum in proposing the election <strong>of</strong> Mr. O'Beirne to honorary<br />
membership <strong>of</strong> the <strong>Society</strong> said that this was indeed a most pleasant<br />
task to him. Mr. O'Beirne was one <strong>of</strong> our founder members and had<br />
served on the Council in many capacities including that <strong>of</strong> President<br />
and the <strong>Society</strong> owed a great deal <strong>of</strong> its present well being to his<br />
efforts on its behalf. In electing him to honorary membership the<br />
<strong>Society</strong> would be paying a well-deserved tribute to a great <strong>Irish</strong> forester.<br />
Mr. Ryan in seconding the proposal said his memory <strong>of</strong> Mr.<br />
O'Beirne would always be associated with forestry in Co. Wicklow<br />
and in particular with the plantings <strong>of</strong> Contorta pine on Ballintownbay<br />
mountain. This was the first introduction <strong>of</strong> the species to Ireland and<br />
could be directly attributed to Mr. O'Beirne's energy and initiative.<br />
He was very glad Mr. O'Beirne had consented to accept honorary<br />
membership and his advice and experience would be invaluable to<br />
the <strong>Society</strong>.<br />
<strong>The</strong> proposal was unanimously carried with acclamation and the<br />
President declared Mr. O'Beirne an honorary member <strong>of</strong> the <strong>Society</strong>.
